Photoconductivity of sensitization (ZnO/ Polystyrene(PS))Composites by Rose Bengal Dye
Main Article Content
Abstract
The photoactive behaviour of rose bengal dye sensitized (ZnO/ Polystyrene (PS)) composites was studied. Two concentrations of composite(30% Zn0/70% PS) and (50% ZnO 150% PS) with (0.05 0.1.0.3,1%)weight percentages of dye were used. The composites are photoconductive and the photoconductivity action spectrum gives the effect of the dye in the visible region.
In the absence of dye within the composites, no photoactivity is
observed in this region of the spectrum. The photoconductivity is affected by the dye content.
Time of flight technique was used to measure response time. The
rise time of the photocurrent is fast and the decay is slow.
