Materials used for the measurement of
radioactivity
, by recording the radioluminescence
. They contain compounds (chromophores
) which combine a high fluorescence
quantum efficiency
, a short fluorescence lifetime
, and a high solubility
. These compounds are employed as solutes in aromatic liquids and polymers to form organic liquid and plastic scintillators, respectively.
