摘要
利用激光显微高温Raman光谱仪 ,测定了TeO2 晶体的常温Raman光谱及高温熔体法生长TeO2 晶体固 液边界层的高温Raman光谱。通过分析 ,指认了TeO2 晶体的常温Raman谱图 2 0 0～ 80 0cm- 1 谱峰的振动模式 ,解析了高温Raman谱图各谱峰的展宽、频移 ,提出了熔体可能的结构基团 ,从而为研究功能性晶体材料生长机理提供了一定依据。
The room temperature and high temperature Raman spectra of solid/melt growth boundary layers of TeO 2 grown from melt were measured by high-temperature laser-micro-Raman spectrum. By analyzing,vibrational modes of the room temperature Raman spectra peaks of TeO 2 crystal from band 200-800 cm -1 were confimed,the expansion and frequency shift of each peak of the high temperature Raman spectra were interpreted and the possible structure group of the melt was proposed.So,certain foundation for studying the growth theory of functional crystal materials was provided.
