Ge-P-S system glass was prepared by melting and sharp cooling method. The glass forming ability and structure of the glass were investigated by DTA, XRD, IR and Raman. The density and chemical stability of the glass were also examined. The results show that the glass exhibits fine glass forming ability and chemical stability. The glass was composed of two different microstructural units, which has great potential of being used in the second-order nonlinear optical apparatus.
