Mixed-Metal Thiophosphate CuCd3PS6: an Infrared Nonlinear Optical Material Activated by Three-in-One Tetrahedra-Stacking Architecture

Abstract

A novel mixed-metal thiophosphate CuCd3PS6 has been first discovered and fully characterized. Careful experimental and theoretical investigations demonstrate that CuCd3PS6 is a benign infrared nonlinear optical material with moderate second harmonic generation response of 0.9 × AgGaS2 at 41-74 μm, large laser damage threshold of 4.1 × AgGaS2, wide band gap of 2.24 eV and low melting point of 603 C. Moreover, first principles calculations indicate CuCd3PS6’s intriguing nonlinear optical performance is activated by its three-in-one tetrahedra-stacking architecture.
