蓝光是构成绚丽多彩自然界的基本色光,与红光、绿光同为平面全色显示的要素,也是一种在许多应用场合不可缺的载息光源。长期以来,制作能耗低、效率高、寿命长、亮度高、结构紧凑、体积小巧、全固体化、使用方便的半导体蓝光发光器件,一直是人们孜孜以求的目标。90年代以来,蓝光发光器件领域出现一系列重大突破,不但实现了半导体蓝光激光器 Blu-ray is the basic color light that forms the colorful natural world. It is also a component of pan-color display with red light and green light. It is also an information-carrying light source indispensable in many applications. For a long time, the production of low energy consumption, high efficiency, long life, high brightness, compact, compact, all-solid, easy to use semiconductor blue light-emitting devices, has always been the goal pursued by people. Since the 90s, a series of major breakthroughs have been made in the field of blue light emitting devices, not only the realization of a semiconductor blue laser
