The High temperature Raman spectra of LBO crystal and melt were studied. The rule of structure change of BGO crystal with increasing temperature was analyzed. The results show that the peaks of spectra move to the lower wavelength and broaden in different degrees. The intensities of spectra peaks decrease,too. In addition,the phase transformation of LBO crystal was studied by using high temperature Raman spectra as well. There is an apparent phase transformation of LBO at 1100K.
