- In this work, hybrid-WOLEDs are fabricated by employing single emitting layers (S-EMLs), which consist of 5-(4-(4,6-diphenyl-1,3,5-triazin-2-yl)phenyl)-10,10-diphenyl-5,10-dihydrodibenzo[b,e][1,4]azasiline (DTPDDA) as a blue thermally activated delayed fluorescent (TADF) emitter and bis(2-methyldibenzo[f,h]quinoxaline) (acetylacetonate)iridium(III) (Ir(MDQ)2acac) as a phosphorescent red emitter. This architecture employs EMLs of a blue exciplex-forming co-host, which are hole transport type host material was 1,3-bis(N-carbazolyl) benzene (mCP) and the electron transport type host material was diphenylphosphine oxide-4-(triphenylsilyl)phenyl (TSPO1). The resulting hybrid-WOLEDs showed maximum external quantum efficiency (EQE) of 6.16% and current efficiency (CE) of 11.58 cd/A with Commission Internationale de L'Eclairage coordinates of (0.32, 0.33).
