Protection against Fluorescence Degradation of Polyvinyltoluene Excimer by uv Light
Department of Instrumentation, Faculty of Engineering, Keio University
(Received June 13, 1973)
The protective effect of additive scintillator solutes on the degradation of polyvinyltoluene (PVT) excimer fluorescence arising from the irradiation by uv light has been investigated in monomer-free PVT systems. In these monomer-free systems, the fluorescence degradation of additive solutes is more intense than that of PVT excimer, and the degradation of PVT excimer fluorescence is protected by the addition of small amounts of anthracene or POPOP. The observed fluorescence degradation and protective effect are explained by a quenching model.
