Published: April 6, 2025

This paper addresses the upconversion of blue light to ultraviolet-C (UVC) with Pr3+-activated materials for antibacterial applications UVC. It discusses processes through which UV radiation provides biocidal effects on microorganisms, along most popular UVC sources employed in these processes. We describe electronic and optical properties Pr3+ ion, emphasizing conditions host material must meet obtain broad intense emission from parity-allowed transitions 4f5d levels provide a list that fulfill conditions. also delineates lanthanide-based upconversion, focusing via 3P0 1D2 intermediate states, suggests routes improving quantum efficiency process. review literature related use antimicrobial photodynamic treatments germicidal effects. Further, we propose spectral overlap between effectiveness curve as criterion assessing potential applications. Finally, this briefly assesses toxicity commonly used preparation materials.
