In this thesis, two novel GeS_2-Ga_2S_3-PbI_2 and GeS_2-Sb_2S_3-CdS pseudo-ternary systems were prepared by melt-quenching technique. Utilizing the techniques such as EPMA, XRD, Raman, DSC-TG, UV-Vis-IR, FT-IR and so on, the relationships between composition, structure and properties of the glasses have been studied systematically. Utilizing the femtosecond time-resolved optical Kerr shutter and Maker fringe methods, the third-order nonlinear optical property and second-harmonic generation of the glasses after electrically/thermally poled have been analyzed, including their dependences on composition and structure.
