Luminescence occurs in some minerals when they are exposed to low-powered sources of ultraviolet or infrared electromagnetic radiation (for example, portable UV lamps), at atmospheric pressure and atmospheric temperatures. This property of these minerals can be used during the process of mineral identification at rock outcrops in the field.
Fluorescent minerals emit visible light when exposed to ultraviolet. Fluorescent marine organisms Fluorescent clothes used in black light theater production, Prague Fluorescence is one of two kinds of photoluminescence , the emission of light by a substance that has absorbed light or other electromagnetic radiation .
This is a list of minerals which have Wikipedia articles. Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various species .
Another class of UV fluorescent bulb is designed for use in bug zappers. Insects are attracted to the UV light, which they are able to see, and are then electrocuted by the device. These bulbs use the same UV-A emitting phosphor blend as the filtered blacklight, but since they do not need to suppress visible light output, they do not use a ...
