摘要
测量了 BSO晶体在常温和高温下宏观拉曼光谱 ,据此分析晶体结构在高温下的变化规律 ,详细实时地测量了晶体在熔化和生长过程中 ,固 /液边界层以及边界层两侧的晶体和熔体的显微拉曼光谱 ,分析得出该晶体生长边界层内的结构特征 。
The Raman spectra of BSO crystal were measured in a temperature range from 293K to 1123K with high temperature Raman spectroscopy and time-resolved detection techniques.Temperature dependence character of Raman spectra and structure of the crystal were investigated.The micro Raman spectra of solid-liquid boundary layer were measured at real time of the BSO crystal growing and melting.The structure character in boundary layer was deduced.The change process of the boundary layer structure from melt structure to crystal structure was analyzed.
