PrTl2InSe4

PrTl2InSe4 is a ternary semiconductor compound containing praseodymium, thallium, indium, and selenium—a research-stage material belonging to the family of complex chalcogenide semiconductors. This compound is primarily of academic and exploratory interest for optoelectronic and photonic applications, where layered or anisotropic chalcogenides are investigated for tunable bandgaps and potential nonlinear optical properties. The material represents an emerging direction in solid-state chemistry where rare-earth and post-transition metal selenides are engineered for next-generation photodetectors, optical modulators, or radiation detectors, though industrial deployment remains limited compared to established alternatives like cadmium telluride or lead halide perovskites.
