英文摘要	High efficiency, stable organic light-emitting diodes (oleds) based on 2-pheyl-4'-carbazole-9-h-thioxanthen-9-one-10,10-dioxide (txo-phcz) with different doping concentration are constructed. the stability of the encapsulated devices are investigated in detail. the devices with the 10 wt% doped txo-phcz emitter layer (eml) show the best performance with a current efficiency of 52.1 cd/a, a power efficiency of 32.7 lm/w, and an external quantum efficiency (eqe) of 17.7%. the devices based on the 10 wt%-doped txo-phcz eml show the best operational stability with a half-life time (lt50) of 80 h, which is 8 h longer than that of the reference devices based on fac-tris(2-phenylpyridinato) iridium(iii) (ir(ppy)(3)). these indicate excellent stability of txo-phcz for redox and oxidation processes under electrical excitation and txo-phcz can be potentially used as the emitters for oleds with high efficiency and excellent stability. the high-performance device based on txo-phcz with high stability can be further improved by the optimization of the encapsulation technology and the development of a new host for txo-phcz.
