Abstract
This work addresses the effects of Gamma radiation on the absorbance and emission properties in layer-by-layer (LbL) poly(p-phenylene vinylene) (PPV)/dodecylbenzenesulfonate (DBS) thin films. The LbL PPV/DBS films were irradiated with 2 Gy and 100 Gy doses, using a 60Co source of Gamma radiation. The effects of irradiation on absorbance and emission of PPV were discussed. The new methodology applied to analyze the effects of radiation on luminescent conjugated polymers provides the possibility to use this material in large-area, low-cost dosimeter sensors.
