Journal ArticleDOI
A novel class of phosphorescent gold(III) alkynyl-based organic light-emitting devices with tunable colour.
Keith Man-Chung Wong,Xiuling Zhu,Ling-Ling Hung,Nianyong Zhu,Vivian Wing-Wah Yam,Hoi Sing Kwok +5 more
TL;DR: A novel class of luminescent cyclometalated gold(III) alkynyl complexes has been demonstrated to possess EL properties and has been employed in the roles of electrophosphorescent emitters or dopants of organic light-emitting diodes (OLEDs) with high brightness and efficiency.
Journal ArticleDOI
Infrared Vibrational Predissociation Spectroscopy of Water Clusters by the Crossed Laser-molecular Beam Technique
TL;DR: In this paper, a rotatable mass spectrometer was used to detect the recoiling fragments off-axis from the molecular beam as a function of laser frequency using a rotable mass analyzer.
Journal ArticleDOI
Nickel induced crystallization of amorphous silicon thin films
TL;DR: In this paper, a-Si under and near the Ni-covered regions was found to be crystallized after heat treatment at 500 ˚°C from 1 to 90 h.
Journal ArticleDOI
Phenanthro[9,10-d]imidazole as a new building block for blue light emitting materials
Zhiming Wang,Ping Lu,Shuming Chen,Zhao Gao,Fangzhong Shen,Wensi Zhang,Yuanxiang Xu,Hoi Sing Kwok,Yuguang Ma +8 more
TL;DR: In this article, a double-layered device based on BPPI showed a higher maximum luminance and a lower turn-on voltage than the multi-layer one with an independent electron injection layer.
Journal ArticleDOI
Red-Light-Emitting Iridium Complexes with Hole-Transporting 9-Arylcarbazole Moieties for Electrophosphorescence Efficiency/Color Purity Trade-off Optimization
Cheuk Lam Ho,Wai Yeung Wong,Z. Q. Gao,Chin H. Chen,Kok Wai Cheah,Bing Yao,Zhiyuan Xie,Qi Wang,Dongge Ma,Lixiang Wang,Xiaoming Yu,Hoi Sing Kwok,Zhenyang Lin +12 more
TL;DR: In this article, the synthesis, structures, photophysics, electrochemistry and electrophosphorescent properties of new red phosphorescent cyclometalated iridium(III) isoquinoline complexes, bearing 9-aryl carbazolyl chromophores, are reported.
