摘　　要：红外非线性光学晶体可以通过频率转换输出中远红外激光,在军事和民用领域都具有重要的应用。硫属化物和磷属化物皆是优秀的中远红外非线性光学材料的候选体系,近二十年来,硫属非线性光学材料得到了广泛研究和应用,然而对磷属非线性光学材料的研究还相当匮乏。本文从新材料探索方面,综述了目前已经报道的磷属非线性光学材料的研究进展,按照晶体结构将其分为三大类,即经典的黄铜矿型结构、同原子键结构以及其他四面体堆积结构。主要讨论了这些化合物的晶体结构、非线性光学性能以及构效关系。最后探讨了磷属红外非线性光学晶体未来的发展方向。Infrared nonlinear optical crystals,which can generate coherent mid-and far-infrared laser through frequency conversion technology,play an increasingly significant role in military and civil fields.Chalcogenides and pnictides have been widely regarded as excellent candidates for mid-and far-infrared nonlinear optical crystals.Over the last two decades,chalcogenide nonlinear optical materials have been widely investigated and applied,however,pnictides have been rarely studied for their nonlinear optical properties.The advances of pnictide nonlinear optical materials has been reviewed from the aspect of new material exploration.These compounds were divided into three types i.e.classical chalcopyrite,structures with homoatomic bonds and structures with tetrahedra units.The crystal structures,physical properties and structure-properties relationships were analyzed.Finally,the future development of pnictide nonlinear optical materials was discussed.
