CsMgGa5S9: a diamond-like network made of mixed tetrahedral units for excellent nonlinear optical properties

CsMgGa5S9 features a diamond-like framework with uniformly stacked mixed tetrahedral units and embedded Cs+ ions. It exhibits a favorable second-harmonic generation response (0.5 × AgGaS2@1910 nm) and a large bandgap (3.12 eV) that yield a high laser-induced damage threshold (8.0 × AgGaS2@1064 nm),...

Summary:CsMgGa5S9 features a diamond-like framework with uniformly stacked mixed tetrahedral units and embedded Cs+ ions. It exhibits a favorable second-harmonic generation response (0.5 × AgGaS2@1910 nm) and a large bandgap (3.12 eV) that yield a high laser-induced damage threshold (8.0 × AgGaS2@1064 nm), making it an excellent nonlinear optical material.
