· K2SmP2S7

K2SmP2S7 is a rare-earth thiophosphate semiconductor compound containing potassium, samarium, phosphorus, and sulfur. This is a research-phase material within the broader family of metal thiophosphates, which are being investigated for their potential in solid-state ionic conductivity, photonic applications, and emerging energy storage devices. The combination of rare-earth and chalcogenide components positions this compound as a candidate for next-generation solid electrolytes, nonlinear optical devices, or radiation-detection applications where sulfide-based frameworks offer advantages over traditional oxide ceramics.
