  • Abstract White organic light-emitting diodes (WOLEDs) are attracting significant attention due to its unique merits of fabrication of large-scale for solid-state lighting sources. In this thesis, a blue-green emissive pyrrole derivative named as npCz was used to develop fluorescent-phosphorescent hybrid WOLED. The emission color of npCz is complementary to the emission color of Ir(pq)2(acac). Thus, the hybrid device utilize npCz as both the fluorescent emissive material and fluorescent host doped with Ir(pq)2(acac).
    This thesis is mainly to optimize the hole and electron transport layer with the analysis of CIE coordinates. Finally,high color rendering warm-white OLED was realized with the following structure: ITO/TCTA (40nm)/ npCz:1 wt% Ir(pq)2(acac) (15nm)/npCz (15 nm)/TmPyPB (50 nm)/LiF(0.5 nm)/Al(130 nm). The device exhibited maximum luminance of 3450 cd/m2, maximum power efficiency of 5.5 lm/W, CIE coordinates of (x,y)=(0.44, 0.44), CRI = 90, and CCT = 3282 K
