A new family of non-centrosymmetric (NCS) compounds Sr6A4M4S16 (A = Ag, Cu; M = Ge, Sn) with mixed tetrahedral anionic ligands (AS4 and MS4) was successfully synthesized and characterized for the first time. All of the compounds exhibit excellent performances as promising infrared nonlinear optical (IR NLO) materials, with large NLO responses (1.1-2.0 × benchmark AgGaS2), high laser damage thresholds (2.0-4.5 × AgGaS2) and wide IR transmission ranges, and are nonhygroscopic. Moreover, their property modulation by the combination of different anionic groups was also discussed.
首次成功合成并表征了一种具有混合四面体阴离子配体（AS4 和 MS4）的新型非中心对称（NCS）化合物 Sr6A4M4S16（A = Ag，Cu；M = Ge，Sn）。所有这些化合物作为有前景的红外非线性光学（IR NLO）材料均表现出优异性能，具有大的 NLO 响应（是基准 AgGaS2 的 1.1 - 2.0 倍）、高激光损伤阈值（是 AgGaS2 的 2.0 - 4.5 倍）和宽红外传输范围，且不吸湿。此外，还讨论了通过不同阴离子基团组合对其性能的调制。
