**Butyl PBD** or **b-PBD** (short for butyl-phenyl-bipheny-oxydiazole[1]) is a [fluorescent](/source/Fluorescence) organic compound used in the [Liquid Scintillator Neutrino Detector](/source/Liquid_Scintillator_Neutrino_Detector) (LSND) at [Los Alamos National Laboratory](/source/Los_Alamos_National_Laboratory), USA.[1]

The fluorescent emission of b-PBD is at *λ*em = 364 nm for excitation at *λ*ex = 305 nm (in [ethanol](/source/Ethanol) solution).[2] As a [scintillant](/source/Scintillant) in the LSND, it was used at a concentration of 31 mg/L (87 μmol/L) dissolved in [mineral oil](/source/Mineral_oil).[1]
