1. A method of making a UV-C emitting emulsion comprising:

mixing a combination of doped strontium aluminate and a stabilized silver solution in a ratio of 18000:1 to 1600:1 of doped strontium aluminate:stabilized silver solution to form an emulsion;

adding silica to the emulsion to form a mixture; and

heating the mixture for 30-50 seconds at 350° F. to 450° F. (176° C. to 232° C.) at a pressure of 30 psig to 70 psig (207 kPa to 483 kPa).
