· JVASP-21533· ErPS4

ErPS4 is a rare-earth phosphide ceramic compound containing erbium and phosphorus, belonging to the family of lanthanide chalcogenides and pnictides. This material is primarily of research and developmental interest rather than established industrial use, with potential applications in optoelectronics, photonics, and solid-state devices where rare-earth-doped ceramics offer advantages in light emission, luminescence, or specialized optical properties. The erbium dopant is particularly valued in fiber-optic amplifier technologies and infrared applications, making ErPS4 a candidate material for next-generation photonic and sensing systems where conventional oxides or fluorides may have limitations.
