UVC Stokes and Anti-Stokes Emission of CaY(PO) Polycrystals Doped with Pr Ions.

The recent COVID-19 pandemic has made everyone aware of the threat of viruses and the growing number of antibiotic-resistant bacteria. It has become necessary to find new methods to combat these hazards. One tool that could be used is UVC radiation, i.

UVC Up-Conversion and Vis-NIR Luminescence Examined in SrO-CaO-MgO-SiO Glasses Doped with Pr.

The application of ultraviolet-C light in the field of surface treatment or photodynamic therapy is highly prospective. In this regard, the stable fluorescent silicate SrO-CaO-MgO-SiO-PrO glasses able to effectively convert visible excitation on the ultraviolet praseodymium emission were fabricated and examined. An unusual wide-range visible-to-UVC up-conversion within 240-410 nm has been achieved in Pr-doped glasses, revealing their potential advantage in different sophisticated disinfection technologies.
