Abstract
Described herein are methods for disinfecting surfaces using a photon-emitting inorganic phosphor-doped substrate material. Methods for preparing the photon-emitting inorganic phosphor-doped substrate materials are additionally described.
Claims29
A method for disinfecting a surface, comprising:
- exposing a surface of a substrate material comprising an inorganic phosphor dopant to a UV light source;
- wherein said exposing causes said inorganic phosphor dopant in said substrate material to emit photons;
- and
- wherein said photons irradiate said surface, thereby disinfecting said surface.
