| 1 | Stable and high performance all-inorganic perovskite light-emitting diodes with anti-solvent treatment显示文摘Optoelectronic applications based on the perovskites always face challenges due to the inherent chemical composition volatility of perovskite precursors. The efficiency of perovskite-based light-emitting diodes(Pe-LEDs) can be enhanced by improving the perovskite film via solvent engineering. A dual solvent post-treatment strategy was applied to the perovskite film, which provides a synchronous effect of passivating surface imperfections and reduces exciton quenching, as evidenced by improved surface morphology and photoluminance. Thus, the optimized Pe-LEDs reach 17,866 cd · m-2 maximum brightness, 45.8 cd · A-1 current efficiency, 8.3% external quantum efficiency, and relatively low turn-on voltage of2.0 V. Herein, we present a simple technique for the fabrication of stable and efficient Pe-LEDs. | Sajid Hussain Ahmad Raza Fawad Saeed Abida Perveen Yan Sikhai Nasrud Din Elias EElemike 黄倩倩 Alagesan Subramanian Qasim Khan 雷威 | 2021 | Chinese Optics Letters2021，19，3： | 0 |
| 2 | Sputtered gold nanoparticles enhanced quantum dot light-emitting diodes显示文摘Surface plasmonic effects of metallic particles have been known to be an effective method to improve the performances of light emitting didoes.In this work,we report the sputtered Au nanoparticles enhanced electroluminescence in inverted quantum dot light emitting diodes(ITO/AuNPs/ZnMgO/QDs/TFB/PEDOT:PSS/Al).By combining the timeresolved photoluminescence,transient electroluminescence,and ultraviolet photoelectron spectrometer measurements,the enhancement of the internal field enhanced exciton coupling to surface plasmons and the electron injection rate increasing with Au nanoparticles’incorporation can be explained.Phenomenological numerical calculations indicate that the electron mobility of the electron transport layer increases from 1.39×10^(-5)cm^2/V·s to 1.91×10^(-5)cm^2/V·s for Au NPs modified device.As a result,the maximum device luminescence is enhanced by 1.41 fold(from 14600 cd/cm^2to 20720 cd/cm^2)and maximum current efficiency is improved by 1.29 fold(from 3.12 cd/A to 4.02 cd/A). | Abida Perveen 张欣 汤加仑 韩登宝 常帅 邓罗根 纪文宇 钟海政 | 2018 | Chinese Physics B2018，27，8： | 0 |
