· JVASP-22941· Rb3SbSe4

Rb3SbSe4 is an inorganic ceramic compound belonging to the family of ternary rubidium antimony selenides, composed of rubidium, antimony, and selenium elements. This material is primarily studied in research contexts for optoelectronic and photonic applications, particularly as a potential infrared transmitter and nonlinear optical material due to the wide bandgap characteristic of selenium-based compounds. Engineers consider this compound for specialized applications where mid-to-far infrared transparency and chemical stability are required, though it remains largely an experimental material with limited industrial-scale production compared to established optical ceramics.
