Sn2Ga2S5: A Type of IR Nonlinear-Optical Material
The deficiency of nonlinear-optical (NLO) materials in the IR region inspires strong research interest in this field. Here, Sn2Ga2S5 (1), crystallizing in the orthorhombic Pna2(1) space group, demonstrates obvious NLO activity, around a maximum of 1.6 times that of AgGaS2 and a strong laser-induced damage threshold of 9.7 times that of AGS. 1 represents the first NLO-active compound in the M(2)(II)M(2)(III)Q(5) (M-II = divalent Ca, Sr, Ba, Pb, Sn, and Eu; mill B, Al, Ga, and In; Q= S and Se) family. The NLO performances of 1 are systematically studied experimentally and theoretically.
