· JVASP-24944· Sm3CuSnS7

Sm₃CuSnS₇ is a quaternary sulfide compound combining samarium (a rare earth element), copper, tin, and sulfur—a material class of significant interest for semiconductor and photovoltaic research. This compound belongs to the family of rare-earth metal chalcogenides, which are being investigated for optoelectronic applications where band-gap engineering and light-harvesting properties are critical. Though not yet a mainstream industrial material, sulfide-based compounds of this type show promise as alternatives to conventional semiconductors in niche applications requiring specific electronic or photonic behavior.
