We demonstrate that solution processed high efficiency and saturated red phosphorescent OLEDs can be achieved using a soluble small molecule (SSM) as the host material. Two structures of ITO /PEDOT /interlayer /SSM:Ir(piq) 3 /LiF /Al and ITO /PEDOT /interlayer /SSM:Ir(piq) 3 /sublimated Balq /sublimated Alq3 /LiF /Al were employed as all soluble processed devices and hybrid devices, respectively. A 6.36 cd/A of maximum luminance efficiency and a 3.22 lm/W of maximum power efficiency were obtained in a hybrid device. The CIE coordinate was (0.67, 0.33).
