摘要
利用共焦显微镜纵向扫描采样手段 ,发展了一种空间分辨 (深度剖析 )光谱方法进行荧光光谱和拉曼光谱的甄别以及它们相应跃迁的指认 .利用荧光的自吸收现象 ,成功地甄别了 Nd:YAG晶体中拉曼和荧光光谱 ,并详尽指认了荧光光谱线的相应跃迁归属 .
A depth analysis spectra method for researching fluorescent and Raman spectra was developed since a self-absorption was often observed in fluorescent spectra of thick solid sample. The intensity change of self-absorption could be observed to explore the secrets of solid state spectra by depth analysis method. The Raman and fluorescent spectra of Nd3+:YAG crystal were measured with 633nm of HN laser and 514. 5nm of Ar+ laser. Some fluorescent lines which possess self-absorption were observed, whose intensity changes with depth of confocal plane. It shows that spatial resolution (depth analysis) method is a powerful experimental means for studying solid state spectroscopy.
