· JVASP-9613· Sr2GeS4

Sr2GeS4 is a strontium germanium sulfide ceramic compound belonging to the family of chalcogenide ceramics, which combine metal cations with sulfur. This material is primarily investigated in research contexts for optoelectronic and photonic applications, where its wide bandgap and sulfide-based composition make it a candidate for infrared transmission windows, nonlinear optical devices, and solid-state laser hosts. Engineers consider this material when conventional oxides are inadequate due to transparency requirements in the mid-to-far infrared spectrum or when unique nonlinear optical properties are needed for frequency conversion and signal processing applications.
