Highly Luminescent Phase-Stable CsPbI3 Perovskite Quantum Dots Achieving Near 100% Absolute Photoluminescence Quantum Yield.
Feng Liu,Yaohong Zhang,Chao Ding,Syuusuke Kobayashi,Takuya Izuishi,Naoki Nakazawa,Taro Toyoda,Tsuyoshi Ohta,Shuzi Hayase,Takashi Minemoto,Kenji Yoshino,Songyuan Dai,Qing Shen +12 more
TL;DR: It is shown that a high room-temperature photoluminescence quantum yield of up to 100% can be obtained in CsPbI3 perovskite QDs, signifying the achievement of almost complete elimination of the trapping defects.
Journal ArticleDOI
Application of graphitic carbon nitride for the removal of Pb(II) and aniline from aqueous solutions
Rui Hu,Rui Hu,Xiangke Wang,Xiangke Wang,Songyuan Dai,Dadong Shao,Tasawar Hayat,Tasawar Hayat,Ahmed Alsaedi +8 more
TL;DR: In this paper, graphitic carbon nitride (g-C3N4) was synthesized from urea with a facile approach and was applied as sorbent to remove Pb(II) and aniline from aqueous solutions.
Journal ArticleDOI
Colloidal Synthesis of Air-Stable Alloyed CsSn1–xPbxI3 Perovskite Nanocrystals for Use in Solar Cells
Feng Liu,Chao Ding,Yaohong Zhang,Teresa S. Ripolles,Taichi Kamisaka,Taro Toyoda,Shuzi Hayase,Takashi Minemoto,Kenji Yoshino,Songyuan Dai,Masatoshi Yanagida,Hidenori Noguchi,Qing Shen +12 more
TL;DR: The synthesis of alloyed perovskite quantum dot (QD), CsSn1-xPbxI3 is reported, which not only can be phase-stable for months in purified colloidal solution but also remains intact even directly exposed to ambient air, far superior to both of its parent Cs SnI3 and CsPbI3 QDs.
