摘要：

High resolution (0.04 cm(-1)) absorption spectroscopy is applied at 9 It to study the role played on the vibrational spectra by impurities (Im), as Si4+, Ge4+, P5+, V5+, and S6+, in BSO, EGO, and BTO sillenite single crystals. Up to three-phonon transitions (overtones of the F mode and combination of F and A modes) are detected for the impurities in ImO(4) tetrahedra. Weak anharmonicity effects are monitored. The presence of Im impurities broadens and shifts the OH-stretching line and induces new bands due to the Im-OH interaction.
