Abstract

Abstract:

The development of electroluminescent light-emitting diodes(LEDs) has been received widespread attention for their potential applications in solid-state lighting technology, full-color displays due to their superior properties such as energy-saving, robust, long-lifetime and environment-friendly features. The notable advantage of electrophosphorescent LEDs is that they can simultaneously utilize both singlet and triplet exciton states which can reach to 100% internal quantum efficiency theoretically compared with those of conventional fluorescent LEDs. Therefore, it is highly desired to develop LEDs based on phosphorescent materials. In this review, we mainly discussed the latest researches on phosphorescent materials, including organometallic complexes, organic molecules, polymers, metal-organic frameworks and carbon quantum dots, etc., and focused on the applications of electrophosphorescent materials in LEDs. We hope this review will provide critical insights to inspire more exciting researches on environment-friendly phosphorescent materials for the application of electrophosphorescent LEDs in the near future.

Key words: electrophosphorescent light-emitting diodes, phosphorescent materials, organometallic complexes, metal-organic frameworks, carbon quantum dots
