Abstract

Abstract : A simple single-emitting layer only containing two phosphors of FMPYPCA (sky blue)/BZQBA (orange red) realizes a high-quality warm-white electroluminescence with CIE x, y of (0.42, 0.45) and very high peak efficiencies of 22.4%/65.4 lm W −1 . Abstract : An efficient white organic light-emitting diode employing a simple/advanced phosphor-only emitting system based on a novel bipolar sky blue phosphorescent host realizes high-quality warm-white electroluminescence emission with very high efficiency.
