Research Progress of Inorganic UV Nonlinear Optical Crystal Materials

紫外(UV)非线性光学(NLO)晶体材料作为全固态紫外激光器的核心部件,在当前的科学和技术应用中发挥着至关重要的作用.目前,传统NLO材料的倍频基因类型相对单一,使得UV NLO材料的实际应用从根本上受到限制.因此,为了突破性能壁垒,亟需发展新的合成方法、开发新的功能基团、拓展新的UV NLO材料体系来进一步筛选新型高性能晶体.对目前UV NLO材料的研究进展进行总结,且结合近年来的相关工作详细描述化学取代定向设计合成策略在开发具有新型结构的高性能UV NLO材料中的应用,并对该领域的未来发展进行展望,强调化学取代定向设计合成策略的优势以及大尺寸晶体生长在光电器件实际应用中的重要性.

Ultraviolet(UV)nonlinear optical(NLO)crystal materials play a vital role in current scientific and technological applications as core components of all-solid-state UV lasers.At present,the types of frequency doubling genes of traditional NLO materials are relatively single,which fundamentally limits the practical application of UV NLO materials.Therefore,in order to break through the performance barriers,it is urgently to develop new synthetic methods,explore new functional groups,and expand new UV NLO material systems to further screen new high-performance crystals.In this paper,the research progress of UV NLO materials is summarized,and combined with the relevant work in recent years,the application of chemical substitution-directed design and synthesis strategies in the development of high-performance UV NLO materials with new structure is described in detail.The future development of this field is prospected,and the advantages of chemical substitution-directed design and synthesis strategies as well as the importance of large-size crystal growth in the practical application of optoelectronic devices are emphasized.
