摘要
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。
This paper mainly introduces the application of the blue eleetroluminescent material, the principle and structure of the electroluminescent device. Blue light-emitting inorganic thin film electroluminescent mate- rials 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 e- mitting material.
