You zhang jing fan6/22/2023 ![]() ![]() Our proposed passivation strategy for large-size perovskite NCs will offer a hopeful strategy for the fabrication of high-performance perovskite devices. Chinese translator Zhang Jing has earned a lot of fans on Chinese social media following her solid performance and accurate translation at the high-level China-US meeting in Alaska on Friday. Using the high quality of Al(acac)3-NC films as emitting layers, the fabricated green perovskite LEDs showed high color purity with a very narrow full width at half maximum (fwhm, 16.8 nm) and effective charge injection with low turn-on voltage (<2.0 V). Al(acac)3-NC film can maintain 94% of the initial PLQY after being stored 3 days under ambient environment. Therefore, the CsPbBr3 NC films with high photoluminescence quantum yield of 88% and the stability of ligand-treated NC film has been significantly promoted as well. To overcome the limitations, the post-treatment strategy is adopted by using aluminium triacetylacetone (Al(acac)3) ligand to exchange the insulating ligand and simultaneously passivate the lead defects of CsPbBr3 NCs with large size. ![]() For more images, visit Zhang Yi Fans Gallery. In Episode 10, she ranked 7 and joined Bonbon Girls 303. However, the weakly bound ligands such as oleic acid and oleylamine of perovskite NCs result in surface defects and hinder the charge carrier transport in the emitting layers. Zhang Yifan () is an idol under Time Fengjun Entertainment and a former contestant on Produce Camp 2020. Cesium lead-halide perovskite nanocrystals (NCs) have emerged as a great potential for next-generation light-emitting diodes (LED) applications due to their high color purity, tunable optical bandgaps, and controllable synthesis. ![]()
