· Pr2 Al1 N1 O3

Pr₂Al₁N₁O₃ is a mixed rare-earth aluminum oxynitride ceramic semiconductor compound combining praseodymium, aluminum, nitrogen, and oxygen. This material belongs to the family of rare-earth nitride ceramics and oxynitrides, which are under active research for high-temperature structural applications and advanced optoelectronic devices where conventional oxides reach performance limits. The incorporation of nitrogen into the aluminum oxide lattice with praseodymium doping offers potential for improved mechanical strength at elevated temperatures and tailored electronic properties, making it of interest for aerospace and high-performance thermal applications.
