In this paper, bulk glasses with composition of Ag x (As0.33S0.335Se0.335)100-x (x = 0–22 at. %) were investigated. Amorphous structure of samples was confirmed by X-ray diffraction analysis. The structure was deduced from Raman spectra measured for all silver contents in As-S-Se matrix. The thermal properties (T g – glass-forming temperature, T s – softening temperature, T c – temperature of crystallization, T m – melting temperature and C p – specific heat capacity), were obtained from modulated differential scanning calorimetry (MDSC) and thermomechanical analysis (TMA). Optical properties were measured by spectral ellipsometric spectroscopy. Refractive index increasing toward higher silver concentration has been shown either. The value of this refractive index difference (Δn) between As33S33.5Se33.5 and Ag22(As0.33S0.335Se0.335)78 is about 0.3.
