Abstract

Abstract : A promising IR nonlinear optical material Li2 ZnGeS4 with a diamond-like configuration and high optical performance is reported. Abstract : Herein, a promising infrared nonlinear optical (IR NLO) material, Li2 ZnGeS4, was successfully synthesized in the typical quaternary diamond-like semiconductor (DLS) system. This material exhibits excellent performances including a wide band gap (3.49 eV), a high laser-damage threshold (LDT, 8 × benchmark AgGaS2 ), and a good NLO effect (0.7 × AgGaS2 ) with phase-matching behavior. Furthermore, based on first principles calculations, the theoretical results are in agreement with the experimental results.
