Highly efficient exciplex organic light-emitting devices: The investigation of the device performance and operational lifetime
碩士 === 國立臺灣科技大學 === 光電工程研究所 === 105 === In this thesis, we use carbazole structure of 4,4’,4”-Tris(carbazol- 9-yl)triphe- nylamine ( TCTA ) as electron acceptor and triazine structure of the hole transport material 2,4,6-tris(3-(1H-pyrazol-1-yl)phenyl)-1,3,5-triazine( 3P-T2T ) as electronic donor.

The two materials were mixed in a co-vapor deposition way to produce highly efficient excitation complexes on the interface, and the exciplex generation was proved by PL spectrum. We analyze the effect on the efficiency by changing the structure of the device to achieve the best efficiency with charge balance. The result of optimized device shows 10% and 29.6% external quantum efficiency with and without green phosphorescence material Ir(ppy)2(acac) and lifetime of ~1400 minutes with initial brightness of 2000 cd/m2. In conclusion, the analysis of films and materials show that the instability of the film and the existence of carrier traps will lead to the life of the devices Chih-Chien Lee 李志堅 2017 學位論文 ; thesis 66 zh-TW |
