luminous paint

   A paint which actually glows in the dark. It contains a phosphor, which is usually a form of zinc or calcium sulfide. It stores light when exposed to it for a length of time, emitting it as a greenish or bluish glow for a relatively short length of time when the light source is removed. Versions of luminous paints with radioactive ingredients are used in situations in which the duration of glow must be prolonged, as on watch faces, but these paints are considerably more hazardous, and less commonly available. Also see fluorescence, fluorescent colors, fugitive colors, glitter, opalescence, and pigment.
