摘要:

A temperature-dependent Raman spectroscopic study on Bi2ZnOB2O6 crystal was carried out to investigate the structure change of the crystal with the increase of temperature. Raman spectra of crystal Bi2ZnOB2O6 were recorded in the spectral range 10-1600 cm-1 at room temperature first. Compared with the vibrational spectra of the referred compounds, satisfactory assignment of most of the high-energy modes to vibrations of Bi-O, B-O, and Zn-O bonds was achieved. In particular, the Raman high-frequency peak located at 1344 cm-1 was attributed to the B-O vibration in the BO3 triangle. This temperature-dependent Raman spectroscopic study was carried out up to 600 ℃. It was found that all the Raman lines exhibit decreases in frequency and the widths of the Raman peaks increase with increasing temperature. No phase transition was observed under 600 ℃.
