We studied structural properties, ≈1.5 μm Stokes and upconversion photoluminescence in Er-doped Ge25Ga8As2S65 glasses at pumping wavelengths of 980 and 1550 nm. GeGaAsS:Er glasses are promising candidates for UCPL applications as they have improved glass-forming ability and thermal properties compared to GeGaS:Er glasses and higher visible transparency than GeGaSbS:Er glasses.
