摘要

High-efficiency white organic light-emitting devices (OLEDs) have great potential for energy saving solid-state lighting and eco-friendly flat-display panels. In addition, white OLEDs are expected to open new designs in lighting technology, such as transparent lighting panels or luminescent wallpapers because of being able to form paper-like thin films. Phosphorescent OLED technology is an imperative methodology to realize high-efficiency white OLEDs because phosphors, such as _fac-tris(2-phenylpyridine)iridium(Ⅲ) [Ir(ppy)_3] and iridium(Ⅲ)bis(4,6-(difluorophenyl)pyridinato-N,C~(2'))picolinate (FIrpic) enable an internal efficiency as high as 100% converting both singlet and triplet excitons into photons. There are two effective approaches to obtain white OLEDs by using phosphors. One is to combine a blue fluorophore and phosphors for the other colors, a so-called hybrid white OLED.
