2. Mercury-vapor lamp - Wikipedia

   en.wikipedia.org/wiki/Mercury-vapor_lamp

   Typical mercury-vapor lamps with an outer envelope made of soda lime or borosilicate glass still allow a relatively large amount of 365 nm UV radiation to escape the lamp. This can cause the accelerated aging of some plastics used in the construction of luminaires, leaving them significantly discolored after only a few years' service.

3. Blacklight - Wikipedia

   en.wikipedia.org/wiki/Blacklight

   A blacklight, also called a UV-A light, Wood's lamp, or ultraviolet light, is a lamp that emits long-wave ultraviolet light and very little visible light. [ 1 ] [ 2 ] [ 3 ] One type of lamp has a violet filter material, either on the bulb or in a separate glass filter in the lamp housing, which blocks most visible light and allows through UV ...

4. Ultraviolet - Wikipedia

   en.wikipedia.org/wiki/Ultraviolet

   Halogen lamps with fused quartz envelopes are used as inexpensive UV light sources in the near UV range, from 400 to 300 nm, in some scientific instruments. Due to its black-body spectrum a filament light bulb is a very inefficient ultraviolet source, emitting only a fraction of a percent of its energy as UV, as explained by the black body ...

5. Extreme ultraviolet lithography - Wikipedia

   en.wikipedia.org/wiki/Extreme_ultraviolet...

   In the 1960s, visible light was used for the production of integrated circuits, with wavelengths as small as 435 nm (mercury "g line"). Later, ultraviolet (UV) light was used, at first with a wavelength of 365 nm (mercury "i line"), then with excimer wavelengths, first of 248 nm (krypton fluoride laser), then 193 nm (argon fluoride laser), which was called deep UV.

6. Light-emitting diode - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode

   The other is to use a phosphor material to convert monochromatic light from a blue or UV LED to broad-spectrum white light, similar to a fluorescent lamp. The yellow phosphor is cerium-doped YAG crystals suspended in the package or coated on the LED. This YAG phosphor causes white LEDs to appear yellow when off, and the space between the ...

7. Ultraviolet photography - Wikipedia

   en.wikipedia.org/wiki/Ultraviolet_photography

   A false color photograph with ultraviolet radiation (335-365nm) mapped to the blue channel, green light (500-600nm) to the green channel and infrared radiation (720-850nm) to the red channel. Ultraviolet photography is a photographic process of recording images by using radiation from the ultraviolet (UV) spectrum only.
