Studies on Novel Blue Phosphorescent Organic Light-emitting Devices
Organic light-emitting devices (OLEDs) have attracted lots of attentions and have been subjects of intensive studies due to their great potential for plat panel display and solid state illumination applications. In this paper, we designed a new type of ultra-thin non doped organic blue electrophosphorescent devices of based on Firpic. We also studied that the impact of object layer thickness fo...
متن کاملEfficient non-doped phosphorescent orange, blue and white organic light-emitting devices
Efficient phosphorescent orange, blue and white organic light-emitting devices (OLEDs) with non-doped emissive layers were successfully fabricated. Conventional blue phosphorescent emitters bis [4,6-di-fluorophenyl]-pyridinato-N,C(2')] picolinate (Firpic) and Bis(2,4-difluorophenylpyridinato) (Fir6) were adopted to fabricate non-doped blue OLEDs, which exhibited maximum current efficiency of 7....
متن کاملPhosphorescent cyclometalated complexes for efficient blue organic light-emitting diodes
Phosphorescent emitters are extremely important for efficient organic light-emitting diodes (OLEDs), which attract significant attention. Phosphorescent emitters, which have a high phosphorescence quantum yield at room temperature, typically contain a heavy metal such as iridium and have been reported to emit blue, green and red light. In particular, the blue cyclometalated complexes with high ...
متن کاملEffect of Interlayer on White Phosphorescent Organic Light-emitting Devices
We demonstrated a novel white electrophosphorescent organic light emitting diodes (PHOLEDs), which structure was ITO/NPB (35 nm)/MCP (5 nm)/Firpic: MCP 10 wt% (15 nm)/ Ir (MDQ)2(acac): TPBI X wt% (2 nm)/Firpic:TPBI 10 wt% (10 nm)/TPBI (40 nm)/LiF (1 nm)/Al (100 nm). The luminescent properties were studied by inserting different doping concentration of the red emitting layer (Ir(MDQ)2(acac):TPBI...
متن کاملPhosphorescent materials for application to organic light emitting devices*
Organic phosphors have demanded the attention of the organic electroluminescence community because they enable ef®ciencies quadruple that of ̄uorescent materials. In this work, we review the categories of organic phosphors: lanthanide complexes, organic phosphors and metal-organic complexes. The characteristics necessary for ef®cient phosphorescence are considered and conclusions are drawn as t...
