Perovskite light-emitting diodes based on spontaneously formed submicrometre-scale structures
Yu Cao,Nana Wang,He Tian,Jingshu Guo,Yingqiang Wei,Hong Chen,Yanfeng Miao,Wei Zou,Kang Pan,Yarong He,Hui Cao,You Ke,Mengmeng Xu,Ying Wang,Ming Yang,Kai Du,Zewu Fu,Decheng Kong,Daoxin Dai,Yizheng Jin,Gongqiang Li,Hai Li,Qiming Peng,Jianpu Wang,Wei Huang,Wei Huang,Wei Huang +26 more
TL;DR: The formation of submicrometre-scale structure in perovskite light-emitting diodes can raise their external quantum efficiency beyond 20%, suggesting the possibility of both high efficiency and high brightness.
Journal ArticleDOI
Employing ∼100% Excitons in OLEDs by Utilizing a Fluorescent Molecule with Hybridized Local and Charge-Transfer Excited State
Weijun Li,Yuyu Pan,Ran Xiao,Qiming Peng,Shitong Zhang,Dongge Ma,Feng Li,Fangzhong Shen,Yinghui Wang,Bing Yang,Yuguang Ma +10 more
TL;DR: In this paper, a twisting donor-acceptor triphenylamine-thiadiazol molecule (TPA-NZP) exhibits fluorescent emission through a hybridized local and charge-transfer excited state (HLCT), which is demonstrated from both fluorescent solvatochromic experiment and quantum calculations.
Journal ArticleDOI
Achieving a Significantly Increased Efficiency in Nondoped Pure Blue Fluorescent OLED: A Quasi-Equivalent Hybridized Excited State
Shitong Zhang,Liang Yao,Qiming Peng,Weijun Li,Yuyu Pan,Ran Xiao,Yu Gao,Cheng Gu,Zhiming Wang,Ping Lu,Feng Li,Shi-Jian Su,Bing Yang,Yuguang Ma +13 more
TL;DR: In this article, a fine excited state modulation was carried out to reach a golden combination of the high PL efficiency locally emissive (LE) component and the high exciton utilizing charge transfer (CT) component in one excited state.
Journal ArticleDOI
Organic Light‐Emitting Diodes Using a Neutral π Radical as Emitter: The Emission from a Doublet
TL;DR: The results pave a new way to obtain 100% internal quantum efficiency of OLEDs, in which an organic open-shell molecule, (4-N-carbazolyl-2,6-dichlorophenyl)bis(2,4-6-trichlor phenyl)methyl (TTM-1Cz) radical, is used as an emitter, to circumvent the transition problem of triplet.
Journal ArticleDOI
Efficient Deep Blue Electroluminescence with an External Quantum Efficiency of 6.8% and CIEy < 0.08 Based on a Phenanthroimidazole–Sulfone Hybrid Donor–Acceptor Molecule
Xiangyang Tang,Qing Bai,Qiming Peng,Yu Gao,Jinyu Li,Yulong Liu,Liang Yao,Ping Lu,Bing Yang,Yuguang Ma,Yuguang Ma +10 more
TL;DR: In this article, a phenanthroimidazole-sulfone hybrid donor-acceptor (D-A) molecule with efficient deep blue emission has been reported, which has been proven to be an effective strategy to obtain high electroluminescence (EL) efficiency.
