PrCuOS

PrCuOS is a mixed-metal oxide semiconductor compound containing praseodymium, copper, oxygen, and sulfur, representing an emerging class of multifunctional oxide-sulfide materials under active research. This material family is primarily investigated for photocatalytic and optoelectronic applications where the combination of rare-earth (Pr) and transition-metal (Cu) sites enables tunable electronic properties and enhanced light absorption. While not yet established in mainstream production, PrCuOS-type compounds show promise as alternatives to conventional semiconductors in applications demanding low-cost earth-abundant elements or enhanced catalytic activity under visible light.
