| 1 | Quenching of the red Mn^(4+) luminescence in Mn^(4+)-doped fluoride LED phosphors显示文摘Red-emitting Mn^(4+)-doped fluorides are a promising class of materials to improve the color rendering and luminous efficacy of white light-emitting diodes(w-LEDs).For w-LEDs,the luminescence quenching temperature is very important,but surprisingly no systematic research has been conducted to understand the mechanism for thermal quenching in Mn^(4+)-doped fluorides.Furthermore,concentration quenching of the Mn^(4+) luminescence can be an issue but detailed investigations are lacking.In this work,we study thermal quenching and concentration quenching in Mn^(4+)-doped fluorides by measuring luminescence spectra and decay curves of K2TiF6:Mn^(4+) between 4 and 600 K and for Mn^(4+) concentrations from 0.01%to 15.7%.Temperature-dependent measurements on K2TiF6:Mn^(4+) and other Mn^(4+)-doped phosphors show that quenching occurs through thermally activated crossover between the ^(4)T_(2) excited state and ^(4)A_(2) ground state.The quenching temperature can be optimized by designing host lattices in which Mn^(4+) has a high 4T2 state energy.Concentration-dependent studies reveal that concentration quenching effects are limited in K_(2)TiF_(6):Mn^(4+)up to 5%Mn^(4+).This is important,as high Mn^(4+)concentrations are required for sufficient absorption of blue LED light in the parity-forbidden Mn^(4+)d–d transitions.At even higher Mn^(4+) concentrations(>10%),the quantum efficiency decreases,mostly due to direct energy transfer to quenching sites(defects and impurity ions).Optimization of the synthesis to reduce quenchers is crucial for developing more efficient highly absorbing Mn^(4+) phosphors.The present systematic study provides detailed insights into temperature and concentration quenching of Mn^(4+) emission and can be used to realize superior narrow-band red Mn^(4+) phosphors for w-LEDs. | Tim Senden Relinde J.A.van Dijk-Moes Andries Meijerink | 2018 | Light(Science & Applications)2018，7，1： | 13 |
| 2 | Water Yield and Sediment Yield Simulations for Teba Catchment in Spain Using SWRRB Model: Ⅰ. Model Input and Simulation Experiment显示文摘Water yield and sediment yield in the Teba catchment, Spain, were simulated using SWRRB (Simulator for Water Resources in Rural Basins) model. The model is composed of 198 mathematical equations. About 120 items (variables) were input for the simulation, including meteorological and climatic factors, hydrologic factors, topographic factors, parent materials, soils, vegetation, human activities, etc. The simulated results involved surface runoff, subsurface runoff, sediment, peak flow, evapotranspiration, soil water, total biomass, etc. Careful and thorough input data preparation and repeated simulation experiments are the key to get the accurate results. In this work the simulation accuracy for annual water yield prediction reached to 83.68%. | ZENG ZHIYUAN and A. M. J.

| 3 | Emerging substance class with narrow-band blue/green-emitting rare earth phosphors for backlight display application显示文摘Solid state lighting (SSL)on the basis of phosphorconverted white light-emitting diodes (pc-wLEDs)is rapidly changing the lighting and display industry.New materials and concepts provide light sources and systems that have unmatched performance and/or functionality [1,2].In addition to the well-known application of pcwLEDs in home and office lighting,these efficient white light sources are also increasingly applied as alternative backlight units in liquid-crystal displays (LCDs),where there is a strong focus on improving resolution,wider color gamut,and decreased power consumption [3]. | Andries Meijerink | 2019 | Science China Materials2019，62，1： | 5 |
| 4 | One ion to catch them all: Targeted high-precision Boltzmann thermometry over a wide temperature range with Gd^(3+)显示文摘Ratiometric luminescence thermometry with trivalent lanthanide ions and their 4f^(n) energy levels is an emerging technique for non-invasive remote temperature sensing with high spatial and temporal resolution.Conventional ratiometric luminescence thermometry often relies on thermal coupling between two closely lying energy levels governed by Boltzmann’s law.Despite its simplicity,Boltzmann thermometry with two excited levels allows precise temperature sensing,but only within a limited temperature range.While low temperatures slow down the nonradiative transitions required to generate a measurable population in the higher excitation level,temperatures that are too high favour equalized populations of the two excited levels,at the expense of low relative thermal sensitivity.In this work,we extend the concept of Boltzmann thermometry to more than two excited levels and provide quantitative guidelines that link the choice of energy gaps between multiple excited states to the performance in different temperature windows.By this approach,it is possible to retain the high relative sensitivity and precision of the temperature measurement over a wide temperature range within the same system.We demonstrate this concept using YAl_(3)(BO_(3))_(4)(YAB):Pr^(3+),Gd^(3+)with an excited 6 PJ crystal field and spin-orbit split levels of Gd^(3+)in the UV range to avoid a thermal black body background even at the highest temperatures.This phosphor is easily excitable with inexpensive and powerful blue LEDs at 450 nm.Zero-background luminescence thermometry is realized by using blue-to-UV energy transfer upconversion with the Pr^(3+)−Gd^(3+)couple upon excitation in the visible range.This method allows us to cover a temperature window between 30 and 800 K. | Dechao Yu Huaiyong Li Dawei Zhang Qinyuan Zhang Andries Meijerink Markus Suta | 2021 | Light(Science & Applications)2021，10，12： | 4 |
| 5 | Water Yield and Sediment Yield Simulations for Teba Catchment in Spain Using SWRRB Model: Ⅱ. Simulation Results显示文摘Simulated results of water yield, sediment yield, surface runoff, subsurface runoff, peak flow, evapo-transpiration, etc., in the Teba catchment, Spain, using SWRRB (Simulator for Water Resources in Rural Basins) model are presented and the related problems are discussed. The results showed that water yield and sediment yield could be satisfactorily simulated using SWRRB model. The accuracy of the annual water yield simulation in the Teba catchment was up to 83.68%, which implied that this method could be effectively used to predict the annual or inter-annual water yield and to realize the quantification of geographic elements and processes of a river basin. | ZENG ZHIYUAN and A.

| 8 | Understanding and tuning blue-to-near-infrared photon cutting by the Tm^(3+)/Yb^(3+) couple显示文摘Lanthanide-based photon-cutting phosphors absorb high-energy photons and‘cut’them into multiple smaller excitation quanta.These quanta are subsequently emitted,resulting in photon-conversion efficiencies exceeding unity.The photon-cutting process relies on energy transfer between optically active lanthanide ions doped in the phosphor.However,it is not always easy to determine,let alone predict,which energy-transfer mechanisms are operative in a particular phosphor.This makes the identification and design of new promising photon-cutting phosphors difficult.Here we unravel the possibility of using the Tm^(3+)/Yb^(3+) lanthanide couple for photon cutting.We compare the performance of this couple in four different host materials.Cooperative energy transfer from Tm^(3+)to Yb^(3+) would enable blue-to-near-infrared conversion with 200% efficiency.However,we identify phonon-assisted cross-relaxation as the dominant Tm^(3+)-to-Yb^(3+) energy-transfer mechanism in YBO_(3),YAG,and Y_(2)O_(3).In NaYF_(4),in contrast,the low maximum phonon energy renders phonon-assisted cross-relaxation impossible,making the desired cooperative mechanism the dominant energy-transfer pathway.Our work demonstrates that previous claims of high photon-cutting efficiencies obtained with the Tm^(3+)/Yb^(3+) couple must be interpreted with care.Nevertheless,the Tm^(3+)/Yb^(3+) couple is potentially promising,but the host material-more specifically,its maximum phonon energy-has a critical effect on the energy-transfer mechanisms and thereby on the photon-cutting performance. | Dechao Yu Ting Yu Arnoldus Jvan Bunningen Qinyuan Zhang Andries Meijerink Freddy T.Rabouw | 2020 | Light(Science & Applications)2020，9，1： | 2 |

| 14 | Assessment of oxide nanoparticle stability in liquid phase transmission electron microscopy显示文摘Studying liquid phase nanoscale dynamic processes of oxide nanoparticles is of considerable interest to a wide variety of fields.Recently developed liquid phase transmission electron microscopy(LP-TEM)is a promising technique,but destabilization of oxides by solid-liquid?electron interactions remains an important challenge.In this work we present a methodology to assess LP-TEM oxide stability in an aqueous phase,by subjecti ng several oxides of tech no logical importa nee to a controlled electr on dose in water.We show a correlati on based on the Gibbs free en ergy of oxide hydrati on that can be used to assess the stability of oxides and dem on strate the existenee of several remarkably stable oxides,with no observable structural changes after one hour of electron beam irradiation in LP-TEM.Rationalizing such destabilization phenomena combined with the identification of stable oxides allows for designing LP-TEM experiments free from adverse beam effects and thus in vestigati ons of numerous releva ntnano scale processes in water. | Mark J.
