Measurements of homogeneous and heterogeneous fluorescence intensity decays using a hybrid time-correlated single photon counting/multifrequency phase fluorometer are reported. A trio of fluorophores exhibiting a range of decay profiles was selected. p-Terphenyl, 1,4-bis[2-(4-methyl-5-phenyloxazolyl)]benzene [(Me)2POPOP], and p-bis[2-(5-phenyloxazolyl)]benzene (POPOP), commonly used reference

Several reports have indicated that scintillators enhance the intensity of radioautographic reactions. If this were the case, the use of scintillators would shorten the exposure time of radioautographs and the production of radioautographs would be accelerated. It was, therefore, decided
