Abstract
The study of glass-forming liquids and their properties is of fundamental importance in materials science and engineering, as glasses have unique properties that make them useful for a wide range of applications. Among the different types of glasses, borate glasses are particularly interesting due to their low melting temperature, high chemical durability, and potential for optical and electronic applications. However, the properties of borate glasses are strongly influenced by their dynamics, which are difficult to study using conventional techniques. Photon correlation spectroscopy (PCS) is a powerful tool that allows the study of the dynamics of liquids at the molecular scale. In this thesis, we investigate the dynamics of alkali borate glass melts using PCS, with the aim of understanding how the molecular rearrangements affect the structural and physical properties of these glasses.
