蓝区无机薄膜电致发光材料研究进展

介绍了蓝区无机薄膜电致发光材料的应用、电致发光器件的发光原理及结构类型,综述了蓝区无机薄膜电致发光材料的种类及其各自存在的问题,重点概述了已实用化的蓝区无机电致发光材料Ga N的研究及应用现状。由于目前多数蓝光芯片核心技术被少数国外公司垄断,我国所掌握的技术离世界先进水平仍有相当大的差距,因此迫切需要国内能够加大对蓝区电致发光材料的研发。

Research progress of the blue area of inorganic thin film electroluminescent material

This paper mainly introduces the application of the blue electroluminescent material, the principle and structure of the electroluminescent device. Blue light-emitting inorganic thin film electroluminescent materials are reviewed and their respective problems are pointed out. The practical application of the GaN blue-light-emitting materials are mainly summarized. At present, most blue-chip core technology is occupied by a few foreign companies, there is still a considerable gap on our available technology from the world's advanced level. So there is an urgent need to increase research and development of the blue electroluminescent light emitting material.
