主　　题：chalcogenide nonlinearity microcrystal defects 

摘      要：To find materials with larger second-order nonlinearity, the Ge-P-S chalcogenide glasses with various ratios of GeS2∶P2S5were prepared by the melt-quenching method. The microstructure and optical properties of these glasses were characterized by XRD, Raman, Vis-NIR spectroscopy and Maker fringe *** second harmonic generation （SHG） was observed in the as-prepared chalcogenide glasses which was ascribed to the thermal stress gradient and/or the microanisotropic defects （such as the lone-pair orbital or the valence alternative pairs） prefer-orientation of the as-prepared glasses.
