| 1 | Photoluminescence and energy transfer of YAG:Ce^(3+),Gd^(3+),Bi^(3+)显示文摘In this study,Gd^(3+)and Bi^(3+)ions act to redshift the emission band to orange region,and to enhance significantly the maximum emission of YAG:Ce^(3+).On account that size mismatch between the host and the doped Gd^(3+)ion,the crystal structure turns soft,and the emission spectra are not tuned from 540 to 570 nm but decreased the emission intensity.Accordingly,an effective way to increase emission intensity is to introduce Bi^(3+)ion into the YAG:Ce^(3+),Gd^(3+)phosphors.Experimental results show partial overlapping between the emission band of Bi^(3+)ion and the excitation band of Ce^(3+)ion,indicating that the energy transfer from Bi^(3+)to Ce^(3+)ions exists in the(Y_(1.94)Ce_(0.06)Gd)Al_(5)O_(12):Bi^(3+)phosphor.Bi^(3+)ion can serve as the activator to provide energy for Ce^(3+)ion via cross relaxation phenomenon.Therefore,the(Y_(1.94)Ce_(0.06)Gd)Al_(5)O_(12):Bi^(3+)phosphor could have potential applications in warm white LEDs. | Meidan Que Wenxiu Que Ting Zhou Jinyou Shao Lingbing Kong | 2016 | Journal of Advanced Dielectrics2016，6，4： | 0 |
| 2 | Effect of the post-annealing temperature on the thermal-decomposed NiO_(x) hole contact layer for perovskite solar cells显示文摘A hysteresis-less inverted perovskite solar cell(PSC)with power conversion efficiency(PCE)of 13.57%was successfully achieved based on the thermal-decomposed NiO_(x) hole contact layer,possessing better electron blocking and hole extraction properties for its suitable work function and high-conduction band edge position.Herein,the transparent and high-crystalline NiO_(x) film is prepared by thermal-decomposing of the solution-derived Ni(OH)_(2) film in our study,which is then employed as hole transport layer(HTL)of the organic–inorganic hybrid PSCs.Reasonably,the post-annealing treatment,especially for the annealing temperature,could greatly affect the Ni(OH)_(2) decomposition process and the quality of decomposed NiO_(x) nanoparticles.The vital NiO_(x) HTLs with discrepant morphology,crystallinity and transmission certainly lead to a wide range of device performance.As a result,an annealing process of 400℃/2 h significantly promotes the photovoltaic properties of the NiO_(x) layer and the further device performance. | Yuxiao Guo Xingtian Yin Jie Liu Wei Chen Sen Wen Meidan Que Yapeng Tian Yawei Yang Wenxiu Que | 2018 | Journal of Advanced Dielectrics2018，8，1： | 0 |
