Organic light-emitting devices that are widely used in solid-state lighting and flat panel display have attracted the attention of researchers because of their advantages such as low voltage, high brightness and high efficiency. Among three primary colors devices, the performances of green and blue organic light-emitting devices are generally higher than those of red devices and basically satisfy the requirements of practical application. Due to the narrow energy gap, it is difficult to realize the matched energy levels between red light-emitting materials and host materials, thus causing the low efficiency and color purity of red devices. In addition, red light-emitting materials are necessary for the realization of white organic light-emitting devices. Therefore, how to realize high performance red light-emitting materials is very important for the development of organic light-emitting devices. Herein we reviewed the recent progress of red iridium complexes phosphorescent materials and devices, especially the strategies of enhancing efficiency and color purity.
- organic electroluminescence,
- red phosphorescent materials,
- high luminescent efficiency,
- stability
