· Pr1 Tl1 Se2

PrTlSe₂ is an experimental ternary semiconductor compound combining praseodymium, thallium, and selenium. This material belongs to the family of chalcogenide semiconductors and is primarily of research interest for investigating novel band structure properties and potential thermoelectric or optoelectronic applications. The thallium-selenium framework combined with rare-earth praseodymium doping represents an emerging material class with limited commercial deployment but potential relevance in solid-state devices where tunable electronic properties are needed.
