摘要

Methods for the quantitative analysis of the IR and Raman spectra of various inorganic glasses to determine physically meaningful optical functions and individual band parameters are discussed. Available approaches to the problem of how to describe the mechanism of formation of the vibrational spectra of glasses (such as the quasi-molecular model, central force model and its recent refinements, and the model of phonon localization regions) are critically discussed. Recent data on band intensities and/or frequencies obtained with these methods for phosphate, borate, and germanate glasses are considered. Trends in the IR and Raman band assignments deduced from the current state of vibrational spectroscopy of glasses are analyzed and structural information obtained by different authors for binary phosphate, borate, and germanate glasses is compared. It is shown that, based on data on individual band parameters obtained, some related optical and dielectric properties of glasses in their transparency range can be calculated and/or modeled. Particular directions that are promising for further development of studies into vibrational spectroscopy of glasses are specified.
