Journal ArticleDOI
Rearranging Low-Dimensional Phase Distribution of Quasi-2D Perovskites for Efficient Sky-Blue Perovskite Light-Emitting Diodes.
Peiyuan Pang,Guangrong Jin,Chao Liang,Bingzhe Wang,Wei Xiang,Dengliang Zhang,Jingwei Xu,Wei Hong,Zewen Xiao,Lei Wang,Guichuan Xing,Jiangshan Chen,Dongge Ma +12 more
TL;DR: Efficient sky-blue perovskite LEDs are reported by rearranging low-dimensional phase distribution in quasi-2Dperovskites by sodium ion and optimizing the phase distribution and film morphology by Pb content.
Journal ArticleDOI
Boosting the performance of CsPbBr3-based perovskite light-emitting diodes via constructing nanocomposite emissive layers
Guangrong Jin,Dengliang Zhang,Peiyuan Pang,Ziqing Ye,Tanghao Liu,Guichuang Xing,Jiangshan Chen,Dongge Ma +7 more
TL;DR: In this article, a facile approach to grow quasi-2D CsPbBr3/Cs4PbBR6 nanocomposite films as the emissive layers (EMLs) for efficient PeLEDs by simply introducing excess CsBr in the precursor solution.
Journal ArticleDOI
Highly Efficient Red Perovskite Light‐Emitting Diodes with Reduced Efficiency Roll‐Off Enabled by Manipulating Crystallization of Quasi‐2D Perovskites
Dengliang Zhang,Lingfeng Chao,Guangrong Jin,Zhaohui Xing,Wei Hong,Yonghua Chen,Lei Wang,Jiangshan Chen,Dongge Ma +8 more
TL;DR: In this article , an efficient red perovskite light-emitting diodes (PeLEDs) with high luminance and low efficiency roll-off was demonstrated by manipulating the crystallization kinetics of phenethylamine bromide (PEABr) incorporated CsPbI3.
Journal ArticleDOI
Low-dimensional phase suppression and defect passivation of quasi-2D perovskites for efficient electroluminescence and low-threshold amplified spontaneous emission.
Guangrong Jin,Tanghao Liu,Yuanzhao Li,Jiadong Zhou,Dengliang Zhang,Peiyuan Pang,Ziqing Ye,Zhaohui Xing,Guichuan Xing,Jiangshan Chen,Dongge Ma +10 more
TL;DR: Significantly reduced nonradiative losses in the quasi-2D perovskite films are achieved by tailoring the low-dimensional phase components and lowering the density of trap states, which enable not only the green light-emitting diodes with a high external quantum efficiency (EQE) of 16.3%, but also the amplified spontaneous emission (ASE) with a low threshold of 2.6 μJ cm-2.
Journal ArticleDOI
Low Threshold, High Q-Factor Optically Pumped Organic Lasers and Exciton Dynamics in OLEDs under High Current Density: Singlet–Triplet Annihilation Effect and toward Electrical Injection Lasing
Yuanzhao Li,Shian Ying,Xiaowei Zhang,Shu Xiao,Dengliang Zhang,Xian Feng Qiao,De Zhi Yang,Junbiao Peng,Dongge Ma +8 more
TL;DR: In this article , the lasing and electroluminescence properties of a new organic gain material, named PIO, with low STA were investigated and it was shown that PIO exhibits remarkable optical gain and EL performance.
