Nanophase separation and effects on properties of Ge–As–Se chalcogenide glasses
Source abstract
Abstract
Abstract Nanophase separation in the bulk Ge–As–Se chalcogenide glasses was observed by SEM and supported by XRD and IR measurements. Effects of nanophase separation on glass transition temperature (Tg), microhardness (Hv), optical band gap (Eopt) and thermal expansion coefficient (α) were investigated in terms of glass rigidity transitions. According to the correlations between the properties and average coordination number Z, it is established that nanophase separation becomes more intensive when Z is larger than 2.64.
