· JVASP-142116· Yb2GeS4

Yb2GeS4 is a rare-earth germanium sulfide ceramic compound belonging to the ternary chalcogenide family. This material is primarily investigated in research contexts for infrared optics and photonic applications, where its wide bandgap and sulfide-based composition offer potential advantages in nonlinear optical devices and mid-to-infrared transparent windows. The incorporation of ytterbium provides rare-earth functionality that may enable luminescent or photonic applications, distinguishing it from simpler binary semiconductors in specialized optical engineering.
