红外激光器在军事和民用领域有着广泛的应用。非线性光学晶体已成为利用典型的变频技术实现红外激光高效输出的关键材料。然而，由于其较低的激光损伤阈值（LDTs）或有害的双光子吸收（TPA），商用红外NLO材料在红外区域受到严重限制。因此，发现具有最佳关键性能（同时具有大NLO系数（dij）和宽光学带隙（Eg））的新型红外NLO材料已成为当务之急。近年来，金属硫族化合物已成为红外NLO材料勘探的丰富来源，已发现数百种金属硫族化合物。根据一种红外NLO材料所需的实验eg（≥3.0 eV）和dij（≥0.5 × AgGaS2）之间的良好平衡，据我们所知，约有49种硫族化合物满足上述条件，同时将范围限制在等于或大于三元体系。我们重点研究了49种化合物的结构-性能关系，结果表明碱或/和碱土金属必须是保持宽的首选阳离子。此外，它们的临界阴离子基团总结如下：(i)典型的四面体MIIIQ4（MIII= Ga, In）或/和MIVQ4（MIV= Si, Ge; Q = S, Se）或ps4单元；（ii）以10个元素为中心（MIIQ4: MII= Zn, Cd）和典型的MIIQ4或mivq4四面体；（三）卤素中心多面体配体。因此，将上述阴离子基团与碱土或/和碱土金属结合成晶体结构，为探索具有优异性能的新型红外NLO材料提供了可行的设计策略。
Infrared (IR) lasers have been widely applied in the many military and civil fields. Nonlinear optical (NLO) crystals have been developed as the critical materials to achieve the efficient IR laser output by the typical frequency-conversion technology. However, commercial IR NLO materials are seriously limited in the IR region because of their low laser-damage thresholds (LDTs) or harmful two-photon absorption (TPA). Therefore, the discovery of new IR NLO materials with optimal key performances (concurrently large NLO coefficient (dij) and wide optical bandgap (Eg)) has become imperative. Recently, metal chalcogenides have become a rich source for exploration of IR NLO materials and hundreds of them have been discovered. Based on the good balance between experimentalEg(≥3.0 eV) anddij(≥0.5 × AgGaS2) required for one IR NLO material, to our best knowledge, about 49 chalcogenides satisfy the above condition while limiting the scope to the equal or greater than ternary system. We focus on the structure-performance relationship for 49 compounds and the result shows that alkali or/and alkaline earth metals must be the preferred cations to maintain the wideEg. Besides, their critical anionic groups are summarized and shown as follows: (i) typical tetrahedral MIIIQ4(MIII= Ga, In) or/and MIVQ4(MIV= Si, Ge; Q = S, Se) or PS4units; (ii)d10elements-centered (MIIQ4: MII= Zn, Cd) and typical MIIIQ4or MIVQ4tetrahedra; (iii) halogen-centered polyhedral ligands. So the combination of above anionic groups and alkali or/and alkaline earth metals into crystal structures produces the feasible design strategy to explore new IR NLO materials with excellent performances.
