“…The 447 nm laser diode excitation was used for S. aureus bacterial solution inactivation with Pr 3+ doped SrSiO 3 powders, 30 while Zhao et al constructed antibacterial wound dressings based on Vis-to-UVC up-conversion in Pr 3+ doped materials. 31 Thus, any improvement in the materials performance in this spectral region could quickly be reflected in the development in technological solutions.…”

Optical upconversion materials doped with lanthanides, such as Yb3+‐Er3+, Yb3+‐Ho3+, and Yb3+‐Tm3+ coped systems, have been intensively studied over the past two decades because they can convert long‐wavelength and low‐energy near‐infrared photons into short‐wavelength and high‐energy visible and UV light. Compared to these double‐doped systems, Pr3+‐doped inorganic materials are gradually gaining popularity and are expected to become a new hotspot in the field of upconversion materials research. However, comprehensive reviews of this issue are scarce. In this minireview, the basic characteristics of transitions of Pr3+ are briefly introduced. Next, it concentrates on strategies that have been explored for regulating the visible‐to‐UV upconversion efficiency. Subsequently, the potential applications of Pr3+‐doped visible‐to‐UV upconversion materials are summarized. Finally, the existing challenges and development trends are highlighted for Pr3+‐based visible‐to‐UV upconversion.

Visible-UVC upconversion polymer films for prevention of microbial infection

Abstract: A wound dressing was prepared using upconversion powder (YSO-Pr) combined with polymer (PVA/SA) to convert visible light to UVC, demonstrating significant inhibition of a wide range of bacteria with no apparent side effects on human cells.
