Wai-Yeung Wong was born in Hong Kong, and graduated with both B.Sc.(Hons.) (1992) and Ph.D. (1995) degrees (Ph.D. supervisor: Prof. Wing-Tak Wong) from the University of Hong Kong. After his postdoctoral work at Texas A&M University in 1996 with Prof. F. Albert Cotton, he worked in the groups of Profs. The Lord Jack Lewis (FRS) and Paul R. Raithby at the University of Cambridge in 1997 as a Croucher Research Fellow. He joined Hong Kong Baptist University as an Assistant Professor in 1998 and is currently a Chair Professor in Chemistry. His research focuses on synthetic inorganic and organometallic chemistry and structural chemistry, with special emphasis on developing metallopolymers and metallophosphors with energy functions and photofunctional properties. He has a distinguished publication record of over 330 scientific articles. He holds the guest professorship of eight institutions in Mainland China. He is also the recipient of the Chemistry of the Transition Metals Award by the Royal Society of Chemistry in 2010, and has won the Croucher Senior Research Fellowship and two Asian Core Program Lectureship Awards in 2009. He is currently a co-editor of the Central European Journal of Chemistry and serves on the editorial/international advisory boards of Macromolecular Rapid Communications, Macromolecular Chemistry & Physics, Dalton Transactions, Journal of Organometallic Chemistry, Comments on Inorganic Chemistry, Current Organic Chemistry, Macromolecular Research, Journal of Inorganic & Organometallic Polymers and Materials and Journal of Cluster Science.

Guijiang Zhou received his Ph.D. degree from Institute of Chemistry, Chinese Academy of Sciences (CAS) in 2003. After a year of postdoctoral research fellow in National Creative Research Center for Light Harvesting Materials in Korea, he held a postdoctoral position in Hong Kong Baptist University with Prof. Wai-Yeung Wong. From April 2007 to September 2008, he was a postdoctoral fellow supported by the Ministry of Science and Education of Spain in University of Murcia. In November 2008, he joined the Department of Applied Chemistry, Xi’an Jiaotong University where he is currently a Professor. Current research interests include functionalized phosphorescent organometallic materials for optical power limiting and electroluminescence.

N2 - White organic light-emitting diodes (WOLEDs) offer a promising avenue to developing future energy-saving solid-state lighting sources because of their intrinsic characters such as low driving voltages, high brightness and efficiency, large area, etc. While commercialization of WOLEDs has attracted tremendous interest in both academic and industrial communities, the discovery of highly efficient phosphors opens up a good channel to meet this target. With the goal towards practical application, many design strategies, including new materials synthesis, judicious design of device configuration, wise management of charges/excitons in different active layers, development of sophisticated and low cost fabrication procedures, etc. have been put forward to achieve high efficiency, good white color stability and quality. In this review, the most recent progress and achievements in various research aspects of the phosphorescent WOLED is presented. Practical applications are enumerated and illustrated by specific examples. The major advances, ongoing challenges and future perspectives of this research frontier are also critically discussed. The present work provides valuable clues to the specialists in the field to develop new routes for future research development of WOLEDs.
