| Abstract: | 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. |
