Abstract

A new quaternary Sn-containing sulfide (Sr₃MnSn₂S₈) was synthesized using a traditional high temperature solid-state method. It crystallizes in the space group I [4 with combining macron] 3d with a = 14.2287(6) Å and Z = 8. Direct extrapolation using the upper tangent revealed an energy band gap at 3.02 eV, larger than that of AgGaS₂ at 2.65 eV. Sr₃MnSn₂S₈ exhibited a strong second harmonic generation response, almost equivalent to that of the benchmark AgGaS₂, and its laser damage threshold was about 3 times that of AgGaS₂.
