In this article, a non-oped blue organic light-emitting device was demonstrated by using a novel electroluminescent material DDPFTBC as an efficient electrofluorescence emitter.Abstract:
A highly efficient nondoped blue organic light-emitting device was demonstrated by using a novel electroluminescent material DDPFTBC as an efficient electrofluorescence emitter. The device in a simple structure of ITO/NPB/DDPFTBC/TPBI/LiF/Al exhibited stable blue emission with the Commission Internationale de L’Eclairage coordinates of (0.18, 0.36), a high current efficiency of 8.7 cd/A, and a high power efficiency of 9.1 lm/W.read more
