Description

technical field

[0001] The invention relates to a novel nonlinear optical crystal silver gallium sulfide phosphide, its preparation and use as a nonlinear optical crystal, belonging to nonlinear optical materials and their synthesis. Background technique

[0002] Infrared nonlinear optics (IR-NLO) crystals are important photoelectric information functional materials, which are widely used in laser frequency conversion, remote communication, non-invasive medical diagnosis, environmental monitoring and laser guidance, and become an indispensable high-tech technology. key material. Understanding and developing infrared nonlinear optics (IR-NLO) crystal materials from the perspective of structure-property relationship has always been a difficult and hot topic in the field of NLO. According to the theory of anionic groups, the planar triangular structural unit is an ideal structural unit, which has a large birefringence and polarizability, and can effectively improve the formati...
