Energy transfer of triplet excitons between EML and ETL materials in single emissive white phosphorescent OLEDs with three primary colors

The performance of collisional quenching process between electron transport materials such as 4,7-diphenyl-l,10-phenanthroline (Bphen), 2',2',2"-(1,3,5-Benzinetriyl)-tris(1-phenyl-1-H-benzimidazole) (TPBi) and l,3,5-tri(3-pyrid-3-yl-phenyl)benzene (TmPyPB) and blue phosphorescent material such as 3,5-difluoro-2-(2-pyridyl)-phenyl-(2-carboxypyridyl) Iridium 111 (Flrpic) was analyzed through spectroscopic study in solution to prove energy loss of …
