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.
Claims19
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 the inorganic phosphor dopant comprises Ca2Al2SiO7 doped with Pr3+;
- 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.
2 more elements
A photon-emitting inorganic phosphor-doped substrate material, comprising:
- a substrate material comprising an inorganic phosphor dopant, wherein said inorganic phosphor dopant in said substrate material is capable of emitting photons upon exposure of a surface of said photon-emitting inorganic phosphor-doped substrate material to a UV light source;
- and
- wherein the inorganic phosphor dopant comprises Ca2Al2SiO7 doped with Pr3+.
A method for preparing a photon-emitting material for surface disinfection, comprising:
- contacting a substrate material with an inorganic phosphor dopant to prepare a photon-emitting inorganic phosphor-doped substrate material, wherein said inorganic phosphor dopant in said photon-emitting inorganic phosphor-doped substrate material is capable of emitting photons upon exposure of a surface of said photon-emitting inorganic phosphor-doped substrate material to a UV light source;
- and
- wherein the inorganic phosphor dopant comprises Ca2Al2SiO7 doped with Pr3+.
