| 1 | Preparation and luminescence characteristics of Sr_3SiO_5:Eu^(2+) phosphor for white LED显示文摘The Sr3SiO5:Eu2+ phosphor was synthesized by high temperature solid-state reaction. The emission spectrum of Sr3SiO5:Eu2+ shows two bands centered at 487 and 575 nm, which well agree with the theoretic values of emission spectrum. The excitation spectrum for 575 nm emission center has several excitation bands at 365, 418, 458 and 473 nm. And the results show that the emission spectrum of Sr3SiO5:Eu2+ is influenced by the Eu2+ concentration. The relative emission spectra of the white-emitting InGaN-based YAG:Ce3+ LED and Sr3SiO5:Eu2+ LED were investigated. The results show that the color development of InGaN-based Sr3SiO5:Eu2+ is better than that of InGaN-based YAG:Ce3+, and the CIE chromaticity of InGaN-based Sr3SiO5:Eu2+ is (x=0.348, y=0.326). | LI PanLai YANG ZhiPing WANG ZhiJun GUO QingLin LI Xu | 2008 | Chinese Science Bulletin2008，53，7： | 16 |
| 2 | Tunable luminescence in co-doped Zn3Al2Ge2O10:Cr3+by controlling crystal field splitting and nephelauxetic effect显示文摘Ce3+/Dy3+/Tb3+/Eu3+/Mn2+and Cr3+ions co-doped Zn3 Al2 Ge2 O10 phosphor were prepared by a hightemperature solid-state method.X-ray diffraction patterns prove the cubic phase structure of prepared Zn3 Al2 Ge2 O10 phosphor,Emission,excitation spectra and decay curves confirm the tunable luminescence.Different degrees of the decrease of emission FWHM in Zn3 Al2 Ge2 O10:0.02 Cr3+,RE(RE=Ce3+,Dy3+,Tb3+,Eu3+)and Zn3 Al2 Ge2 O10:0.02 Cr3+,Mn2+are observed.The reason of variable FWHM is the effect of crystal field splitting and nephelauxetic effect,and the nephelauxetic effect is dominant.Therefore,the emission FWHM decreases with the increasing concentration of Mn2+/Tb3+/Eu3+in Zn3 Al2 Ge2 O10:0.02 Cr3+,and for Zn3 Al2 Ge2 O10:0.02 Cr3+,Ce3+and Zn3 Al2 Ge2 O10:0.02 Cr3+,Dy3+,it is a constant.The variation of Zn3 Al2 Ge2 O10:0.02 Cr3+,Tb3+is more obvious than that of Zn3 Al2 Ge2 O10:0.02 Cr3+,Eu3+,because Tb3+ion has smaller electronegativity.Thus,the tunable luminescence of Cr3+can be realized by co-doping different ions.And these phosphors have potential applications in light-emitting diodes for plant growth. | Qiongyu Bai Suling Zhao Zheng Xu Panlai Li | 2020 | Journal of Rare Earths2020，38，12： | 3 |

| 4 | Luminescence,Concentration Quenching and Thermal Stability of White Emitting Phosphor Ba_2Ca(BO_3)_2:Dy^(3+)显示文摘A white emitting phosphor Ba2Ca(BO3)2:Dy3+ was synthesized via a high temperature solid state reaction at 1000℃ for 5 h. The luminescence, mole fraction quenching and thermal stability of Ba2Ca(BO3)2:Dy3+ were investigated. According to the phase composition analyzed by X-ray powder diffraction, there is no crystalline phase except Ba2Ca(BO3)2 in the sample. Ba2Ca(BO3)2:Dy3+ can produce white emission under 348 nm excitation. The emission intensities of Ba2Ca(BO3)2:Dy3+ are affected by Dy3+ concentration. The concentration quenching effect was analyzed, and the concentration quenching mechanism was verified as dipole-dipole interaction. The critical distance(R c) obtained based on the crystal structure data is 2.911 nm. At 150℃, the emission intensity of Ba2Ca(BO3)2:Dy3+ is 68.0% of the initial value at room temperature. The activation energy for the thermal quenching calculated is 0.202 e V. Moreover, the CIE chromaticity coordinates of Ba2Ca(BO3)2:Dy3+ locate in the white region of(0.319, 0.356). | SONG Huiling ZHOU Fen CAO Heying GUO Mingchao ZHAO Jiawei WANG Zhijun LIU Haiyan GAO Shaojie LI Panlai | 2015 | Journal of the Chinese Ceramic Society2015，，2： | 1 |

| 13 | Luminescence Properties of Red Emitting Phosphor KMgLa(PO_4)_2:Sm^(3+) for White LEDs显示文摘A series of Sm^(3+) doped KMgLa(PO_4)_2 have been prepared via a high-temperature solid-state method.The phase of the phosphor was characterized by X-ray diffraction,and the spectra of phosphors were measured by the fluorescence spectrophotometer.Under 402 nm near-ultraviolet excitation,KMgLa(PPO_4)_2:Sm^(3+) shows orange-red emission,and the emission peak locates at 600 nm,which is associated to the ~4G_(2/5)→~6H_(9/2) transition of Sm^(3+).The emission intensity of phosphors can be tuned by changing the Sm^(3+) concentration,and the optimal Sm^(3+) doping concentration is about0.01.The concentration quenching phenomenon was observed in KMgLa(PO_4)_2:Sm^(3+),and the critical distance is calculated to be about 3.082 nm.The CIE chromaticity coordinates of phosphors shift from red to pink with the Sm^(3+) concentration increasing.All the results suggest that it could be a potential application in white LEDs manufacture. | LI Ting LI Yue SHI Xian TIAN Yinghe BAI Qiongyu Yuan Xiaoxian WANG Zhijun LI Panlai YANG Zhiping | 2016 | Journal of the Chinese Ceramic Society2016，，3： | 0 |
| 14 | Luminescence, Energy Transfer and Concentration Quenching of Red Emitting Phosphor Ba_3Eu(PO_4)_3:Tb^(3+)显示文摘A red emitting phosphor of Ba_3Eu(PO_4)_3:Tb^(3+) was synthesized by a solid state method. The energy transfer from Tb^(3+) to Eu3+ in Ba_3Eu(PO_4)_3:Tb^(3+) was proved by the spectral properties and decay curves. The emission intensity of Ba_3Eu(PO_4)_3 is enhanced by doping Tb^(3+) as a sensitizer. For Ba_3Eu(PO_4)_3:Tb^(3+), the ~5D_3→~7F_J transition of Tb^(3+) occurs, and the corresponding emission intensities can be tuned when Tb^(3+) content increases, and the concentration quenching effect appears. However, for the ~5D_4→~7F_J transition of Tb^(3+), its intensity straight increases with increasing Tb^(3+) content. For Ba_3Eu(PO_4)_3:Tb^(3+), the values of CIE chromaticity coordinates are similar to those of commercial red phosphors of Sr_2Si_5N_8:Eu^(2+) and Y_2O_2S:Eu^(3+). The results indicate that this red emitting phosphor has a potential application for white LEDs. | LI Yamin LI Xiang SHI Xian ZHANG Huan TIAN Zhi QI Shuai YUAN Xiaoxian LI Panlai WANG Zhijun YANG Zhiping | 2016 | Journal of the Chinese Ceramic Society2016，，1： | 0 |
| 15 | Improvement Up-conversion Luminescence Properties of SrIn_2O_04:Er^(3+) by Doping Yb^(3+) as Sensitizer显示文摘A series of Yb^(3+)/Er^(3+) or Er^(3+) doped SrIn_2O_4 were synthesized by a high temperature solid state method.The up-conversion luminescence property and the phase formation of SrIn_2O_4:Er^(3+) and SrIn_2O_4:Yb^(3+),Er^(3+) were investigated by X-ray diffraction(XRD) and spectral methods.The XRD pattern shows that incorporating different amounts of Yb^(3+)and Er^(3+) have no influence on the phase formation of SrIn_2O_4.The up-conversion luminescence spectrum of SrIn_2O_4:Er^(3+) presented a weak luminescence due to ground state absorption of Er^(3+).However,Yb^(3+)/Er^(3+) codoped SrIn_2O_4 depicted the green(525 and 551 run) and red(662 nm) up-conversion luminescence which were assigned to the energy transfer from the Yb^(3+) transition ~2F_(7/2)-~2F_(5/2) to the Er^(3+) transitions ~2H_(11/2)-~4I_(15/2) and ~4F_(9/2-~4I_(15/2),respectively.The possible up-conversion luminescence mechanism of SrIn_2O_4:Yb^(3+),Er^(3+) was analyzed.All results could be helpful to the development of up-conversion luminescence materials. | QI Shuai TIAN Yinghe LI Yong ZHANG Huan LI Xiang YOU Jianqi YUAN Xiaoxian WANG Zhijun LI Panlai LIU Haiyan | 2016 | Journal of the Chinese Ceramic Society2016，，2： | 0 |
| 16 | Beam fanning effect and image storage in Ce:KNSBN crystal显示文摘A non-synchronously-numerating experimental system is applied in this research.The effect of the incident beam intensity I and the beam incident angleθon beam fanning effect is investigated with a singular beam incident on Ce:KNSBN crystal.The results show that the beam fanning effect strongly depends on I andθ.The threshold effect of I for the beam fanning in Ce:KNSBN crystal is observed,and the threshold intensity of incident beam keeps the same value of 38.2 mW/cm 2 for differentθ,and the steady beam fanning intensity Ifsat reaches a peak atθ=15°under the same I.In addition,the effect of the incident beam modulated on the beam fanning noise and holographic storage in Ce:KNSBN crystal is studied.And the results suggest that the beam fanning noise is effectively suppressed,and the quality of the reappearance image is greatly improved. | LI PanLai GUO QingLin WANG ZhiJun PANG LiBin LIANG BaoLai | 2007 | Chinese Science Bulletin2007，52，8： | 0 |
