2. Scintillator - Wikipedia

   en.wikipedia.org/wiki/Scintillator

   The second crystal from the left is targeted by an UV source and shines brightly in visible light. A scintillator (/ ˈ s ɪ n t ɪ l eɪ t ər / SIN-til-ay-ter) is a material that exhibits scintillation, the property of luminescence, [1] when excited by ionizing radiation. Luminescent materials, when struck by an incoming particle, absorb its ...

3. Fluorescent lamp - Wikipedia

   en.wikipedia.org/wiki/Fluorescent_lamp

   A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor, to produce ultraviolet and make a phosphor coating in the lamp glow.

4. Scintillation counter - Wikipedia

   en.wikipedia.org/wiki/Scintillation_counter

   A scintillation counter is an instrument for detecting and measuring ionizing radiation by using the excitation effect of incident radiation on a scintillating material, and detecting the resultant light pulses. It consists of a scintillator which generates photons in response to incident radiation, a sensitive photodetector (usually a ...

5. Phosphor - Wikipedia

   en.wikipedia.org/wiki/Phosphor

   Cathode-ray tubes produce signal-generated light patterns in a (typically) round or rectangular format. Bulky CRTs were used in the black-and-white television (TV) sets that became popular in the 1950s, developed into color CRTs in the late 1960s, and used in virtually all color TVs and computer monitors until the mid-2000s.

   en.wikipedia.org/wiki/Everhart–Thornley_detector

   Disassembled Everhard-Thornley detector from (Philips XL30), showing (from left) the +300V grid and tube, transparent cylindrical light guide, golden clamping nut, and the internal assembly with scintillator disc (+10 kV) on the top. A common photomultiplier would be on the rear side of light guide and is not shown.

8. Nanophotonic scintillators - Wikipedia

   en.wikipedia.org/wiki/Nanophotonic_scintillators

   That is, instead of having an isotropic emission of light due to a high-energy radiation that reaches the scintillator, the emission itself is directional towards the location of the detector through a reduction of the emission into directions which experience total internal reflection between the scintillator and its surrounding materials ...

9. Fluorescent-lamp formats - Wikipedia

   en.wikipedia.org/wiki/Fluorescent-lamp_formats

   In the 1970s, Thorn Lighting introduced an energy-saving 8 ft retrofit tube in Europe. Designed to run on the existing 125 W (240 V) series ballast but with a different gas fill and operating voltage, the tube operated at only 100 W. Increased efficiency meant that the tube produced only 9% lumen reduction for a 20% power reduction. [ 7 ]
