Abstract
The influence of annealing on the photoconductivity of the composite materials of zinc oxide dispersed in polymethylmethacrylate (ZnO/PMMA) has been investigated. As a result, it was revealed that the photoconductivity of ZnO/PMMA composites was remarkably enhanced by annealing. From the experimental results of temperature dependences of the dark current, the dark current-voltage characteristics, the light wavelength characteristics and the photocurrent-light intensity characteristics, the photoconductive mechanism of the annealed ZnO/PMMA composites was discussed.
