空间分辨（深度剖析）光谱法在拉曼和荧光光谱中的应用

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。

ANALYSIS OF FLUORESCENT AND RAMAN SPECTRA WITH SPATIAL RESOLUTION (DEPTH ANALYSIS) METHOD

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.
