PrTlSe2 is a ternary semiconductor compound composed of praseodymium, thallium, and selenium, belonging to the rare-earth chalcogenide family of materials. This is a research-phase compound with limited industrial deployment; it is primarily investigated in materials science for potential applications in infrared optics, thermoelectric devices, and solid-state electronics where rare-earth semiconductors offer unique electronic band structures and optical properties. The material's combination of a rare-earth element with heavy chalcogens positions it as a candidate for exploring novel properties in niche photonic and quantum applications, though alternative rare-earth or lead-based semiconductors currently dominate commercial markets.
