Research Abstract

In amorphous materials, an asymmetrical broad band is observed in a low-frequency region of inelastic light scattering spectra, the so-called"Boson peak". Since the Boson peak reflects the medium-range structure of the amorphous matter, it is expected that the Boson peak provides a significant insight about the glass. crystal transition state. Therefore, in this study, in-situ measurement of Boson peak in oxide glasses was performed during heating/crystallization for the purpose of understanding the structural inhomogeneity in oxide glass and its crystallization dynamics.
