Title:
COMPOSITION, FILM, ORGANIC LIGHT EMITTING ELEMENT, METHOD FOR PROVIDING LIGHT EMITTING COMPOSITION, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/157593
Kind Code:
A1
Abstract:
Superior durability is demonstrated by an organic light emitting element that uses a light emitting composition including both a first compound with a PBHT value greater than 0.730 and a second compound for which ES1 is smaller than for the first compound and ΔEST is less than 0.20 eV. ES1 is the minimum excited singlet energy level, and ΔEST is the difference between the minimum excited singlet energy level and the minimum excited triplet energy level.
