A touchscreen cover, comprising:

• a top side facing the user of a touchscreen;
• a bottom side facing the touchscreen;
• and
• at least one material for emitting energy having a wavelength ranging from 100-400 nm, that is in optical communication with the top side,
• wherein the touchscreen cover is substantially transparent and adapted to substantially cover the touchscreen, the touchscreen cover having a thickness that allows user inputs to be transmitted to said touchscreen,
• wherein the at least one material for emitting energy having a wavelength ranging from 100-400 nm comprises a glass or plastic resin and at least one phosphor which is embedded in, or coated on the glass or plastic resin,
• wherein said at least one phosphor is configured to convert an initial electromagnetic energy (A) that is emitted from the touchscreen itself to a different electromagnetic energy (B), said different electromagnetic energy (B) comprising UVB, UVC, or combinations thereof.
