Structural relaxation of scintillating glass with a nominal composition of Ce:NaGd(PO3)4 was experimentally studied using non-isothermal TMA, the relaxation process was described by the Tool-Narayanaswamy-Mazurin model and distribution of relaxation times was expressed by the empirical Kohlrausch-Williams-Watts function. Model parameters and material constants were obtained by the nonlinear regression analysis of thermo-mechanical data.
