· Nd4(GeS4)3

Nd4(GeS4)3 is a rare-earth germanium sulfide semiconductor compound containing neodymium, germanium, and sulfur. This is a research-phase material studied for its potential in infrared photonics and nonlinear optical applications, where the rare-earth doping and sulfide chemistry offer transparency and optical response in wavelength regions inaccessible to common semiconductors. The material family is notable for combining rare-earth ion luminescence with chalcogenide semiconductor properties, making it of interest to researchers exploring next-generation photonic devices, though practical industrial adoption remains limited.
