Abstract :
The characterization of the iridium compounds bearing 2,3-diphenylquinoxaline units is presented here to afford vivid-red emitting phosphors with exceedingly high quantum yields and enhanced radiative transition performance. The series of 2,3-diphenylquinoxalinato-iridium phosphors are proposed to realize an efficient, bright and vivid-red emission.
