Hairen Tan,Ankit Jain,Oleksandr Voznyy,Xinzheng Lan,F. Pelayo García de Arquer,James Z. Fan,Rafael Quintero-Bermudez,Mingjian Yuan,Bo Zhang,Yicheng Zhao,Fengjia Fan,Peicheng Li,Li Na Quan,Yongbiao Zhao,Zheng-Hong Lu,Zhenyu Yang,Sjoerd Hoogland,Edward H. Sargent +17 more
TL;DR: A contact-passivation strategy using chlorine-capped TiO2 colloidal nanocrystal film that mitigates interfacial recombination and improves interface binding in low-temperature planar solar cells is reported.
Journal ArticleDOI
Highly Efficient Perovskite-Quantum-Dot Light-Emitting Diodes by Surface Engineering
Jun Pan,Li Na Quan,Li Na Quan,Yongbiao Zhao,Wei Peng,Banavoth Murali,Smritakshi P. Sarmah,Mingjian Yuan,Lutfan Sinatra,Noktan M. Alyami,Jiakai Liu,Emre Yassitepe,Zhenyu Yang,Oleksandr Voznyy,Riccardo Comin,Mohamed N. Hedhili,Omar F. Mohammed,Zheng-Hong Lu,Dong Ha Kim,Edward H. Sargent,Osman M. Bakr +20 more
TL;DR: A two-step ligand-exchange strategy is developed, in which the long-carbon- chain ligands on all-inorganic perovskite quantum dots (QDs) are replaced with halide-ion-pair ligands.
Journal ArticleDOI
Color-stable highly luminescent sky-blue perovskite light-emitting diodes
Jun Xing,Yongbiao Zhao,Mikhail Askerka,Li Na Quan,Xiwen Gong,Weijie Zhao,Jiaxin Zhao,Hairen Tan,Guankui Long,Liang Gao,Liang Gao,Zhenyu Yang,Oleksandr Voznyy,Jiang Tang,Zheng-Hong Lu,Qihua Xiong,Qihua Xiong,Edward H. Sargent +17 more
TL;DR: Perovskite light-emitting diodes show promising color tunability and device performance but suffer from emission color shift at higher driving voltages, so color stable sky-blue PeLEDs achieved by enhancing the phase monodispersity of quasi-2D perovskites thin films are reported.
Journal ArticleDOI
Low-power continuous-wave nonlinear optics in doped silica glass integrated waveguide structures
Marcello Ferrera,Luca Razzari,Luca Razzari,David Duchesne,Roberto Morandotti,Zhenyu Yang,Marco Liscidini,John E. Sipe,Sai T. Chu,Brent E. Little,David J. Moss,David J. Moss +11 more
TL;DR: In this paper, the authors present the first demonstration of nonlinear optics in integrated silica-based glass waveguides using continuous-wave light, and demonstrate four-wave mixing with low (5mW) continuous-Wave pump power at λ = 1,550nm, in high-index, doped silica glass ring resonators.
