Abstract:

The Raman spectrum of lithium Diborate (Li2B2O7:LBO) has been determined. The different internal modes have been analyzed. It is proved that the Raman spectra consist of BO3triangular and BO4 tetrahedron internal modes. Because of the effect of delocalization of electron, the LBO crystal has nonliner characters, but from the B-O streching vibration, it can be seen that its nonliner characters is not strong.

Key words: Lithium diborate single crystal, Normal vibration, Raman spectrum
