Butyl PBD or b-PBD (short for butyl-phenyl-bipheny-oxydiazole[1]) is a fluorescent organic compound used in the Liquid Scintillator Neutrino Detector (LSND) at Los Alamos National Laboratory, USA.[1]
The fluorescent emission of b-PBD is at λem = 364 nm for excitation at λex = 305 nm (in ethanol solution).[2] As a scintillant in the LSND, it was used at a concentration of 31 mg/L (87 μmol/L) dissolved in mineral oil.[1]
