即PL，是用紫外、可见或红外辐射激发发光材料而产生的发光，在半导体材料的发光特性测量应用中通常是用激光（波长�?25nm�?32nm�?85nm 等）激发材料（如GaN、ZnO、GaAs 等）产生荧光，通过对其荧光光谱（即PL 谱）的测量，分析该材料的光学特性，如禁带宽度等。光致发光可以提供有关材料的结构、成分及环境原子排列的信息，是一种非破坏性的、高灵敏度的分析方法，因而在物理学、材料科学、化学及分子生物学等相关领域被广泛应用。传统的显微光致发光光谱仪都是采用标准的显微镜与荧光光谱仪的结合，但是传统的显微镜在材料的PL 谱测量中，存在很大的局限性，比如无法灵活的选择实验所需的激光器（特别对于UV 波段的激光器，没有足够适用的配件），无法方便的与超低温制冷机配合使用，采用光纤作为光收集装置时耦合效率太低等等问题，都是采用标准显微镜难以回避的问题、�/span></span></p><p><span> 北京卓立汉光仪器有限公司结合了公司十余年荧光光谱仪和光谱系统的设计经验和普遍用户的实际需求，推出了‛�/span><span><strong>Flex One(
