Abstract We introduce gadolinium in chalcogenide glasses to exert unexpectedly the multiple magical effects on both optical and thermal mechanical properties of chalcogenide glasses. Notable increases in transition temperature T_g and microhardness H_v were observed due to structural densification and microcrystallization. Calculated molar volume values, differential scanning calorimetry and x-ray diffraction measurements provide supporting evidence. Gadolinium also acts as an oxygen getter by removing or weakening oxygen-related absorption bands, which is associated with the higher negative electrode potential.
