摘要 | We fabricated three phosphorescent blue organic light-emitting devices based on blue phosphor of iridium(III) bis[(4,6-difluorophenyl)-pyridinato-N,C2'](Firpic) with different electron transporting layer(ETL) materials. By analyzing efficiency curves and spectral characteristics, the significant effect of ETL on many aspects of device performance was demonstrated. With optimized ETL, the characteristics of devices, such as voltage and efficiency were significantly improved. Combined with a yellow phosphor of iridium(III) bis(4-phenylthieno[3,2-c]pyridinato-N,C2') acetylacetonate(PO-01), phosphorescent white organic light-emitting devices(PhWOLEDs) were obtained. Then, with an aim to promote the performance of the PhWOLEDs, a thin layer of 4,4',4"-tri(N-carbazolyl)-triphenylamine(TCTA) was introduced between two light emission layers, and the diffusion of excitons was confined. The outperformance device fabricated with 4,7-diphenyl-1,10-phenanthroline(Bphen) as the electron transporting layer exhibited a peak current efficiency of 36.6 cd/A, a peak power efficiency of 19.2 lm/W, and the International Commission on Illumination coordinates(0.37, 0.46). |
