P-204L:Late-News Poster: Highly Efficient, Long-Lifetime and Deep-Blue Emissive Materials for OLED Display and Lighting Applications

Abstract

A new deep-blue dopant BD with a singlet energy gap of about 2.81 eV was designed and developed. The electroluminescent devices of BD, sensitized by a host material BH, exhibited saturated color with CIEy of 0.144 and 8.11% EQE. The best blue device lifetime under 1000 cd/m 2 is 15000 hr.
