使用光栅单色仪测量红宝石晶体的吸收和发射光谱

摘要

使用WDS-8型光栅单色仪测量了室温下红宝石晶体的吸收光谱和发射光谱。通过该实验，学生在了解光致发光原理及光致发光材料光谱特性的同时，掌握单色仪的使用方法和技巧。%The absorption spectrum and emission spectrum of ruby crystal were measured using WDS-8 type grating monochromator .This experiment could enable students to understand the princi-ple of photoluminescence and the spectral properties of optical materials ,master the technique and op-eration method of monochromator .
