Butyl PBD
Encyclopedia
Butyl PBD or b-PBD is a fluorescent
organic compound used in the Liquid Scintillator Neutrino Detector (LSND) at Los Alamos National Laboratory
, USA.
The fluorescent emission of b-PBD is at λem = 364 nm for excitation at λex = 305 nm (in ethanol
solution). As a scintillant in the LSND, it was used at a concentration of 31 mg/l (87 µmol/l) dissolved in mineral oil

Fluorescence
Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation of a different wavelength. It is a form of luminescence. In most cases, emitted light has a longer wavelength, and therefore lower energy, than the absorbed radiation...

Ethanol
Ethanol, also called ethyl alcohol, pure alcohol, grain alcohol, or drinking alcohol, is a volatile, flammable, colorless liquid. It is a psychoactive drug and one of the oldest recreational drugs. Best known as the type of alcohol found in alcoholic beverages, it is also used in thermometers, as a...
