Ultraviolet (UV, λ < 400 nm) and deep-UV (λ < 200 nm) nonlinear optical (NLO) crystals have the ability to convert the wavelength of laser to output UV or even deep-UV coherent light by means of frequency doubling and play a significant role in solid-state lasers. Recently, borate-based short-wavelength NLO crystals have attracted considerable attention owing to their diverse structures and tunable performance. For example, fluorooxoborates, hydroxyborates, hydroxyfluorooxyborates, borophosphates, borosilicates, borosulfates and fluoroborophosphates display rich structure types and enhanced optical properties. In this review, recently discovered borate-based NLO crystals with a modified boron–oxygen skeleton are overviewed and analyzed, including their crystal structure features, short-wave cutoff edges, birefringence and second harmonic generation (SHG) responses. This review presents the positive influence of boron–oxygen skeleton modification on the structure–property relationship. We hope to provide the recent progress in the crystal chemistry of borate-based short-wavelength NLO crystals and facilitate the discovery of promising UV and even deep-UV NLO candidates.

硼氧骨架修饰硼酸盐基短波长非线性光学晶体的最新进展
紫外线 (UV, λ < 400 nm) 和深紫外 ( λ< 200 nm）非线性光学（NLO）晶体具有通过倍频的方式转换激光波长以输出紫外甚至深紫外相干光的能力，在固态激光器中发挥着重要作用。近年来，硼酸盐基短波长非线性光学晶体由于其多样化的结构和可调的性能而引起了广泛的关注。例如，氟氧硼酸盐、羟基硼酸盐、羟基氟氧硼酸盐、硼磷酸盐、硼硅酸盐、硼硫酸盐和氟硼磷酸盐显示出丰富的结构类型和增强的光学性质。在这篇综述中，对最近发现的具有改性硼氧骨架的硼酸盐基非线性光学晶体进行了概述和分析，包括它们的晶体结构特征、短波截止边缘、双折射和二次谐波产生（SHG）响应。本综述介绍了硼-氧骨架修饰对结构-性能关系的积极影响。我们希望提供基于硼酸盐的短波长非线性光学晶体的晶体化学的最新进展，并促进有前途的紫外甚至深紫外非线性光学候选材料的发现。
