Electro-optical study of composites of ZnO nanoparticles and P3HT at high ratio.
High ZnO ratios leads to connecting electrical paths of both materials.
Highest UV response was observed for an optimal P3HT:ZnO ratio of 1:8 w/w.
Dynamic response study by using UV pulsing in white-light background and vice versa.
Anomalous response was explained by charge transport mechanisms for such composites.
