内容記述 Photoconduction processes in various polymers were discussed in the range from ultraviolet to infrared wavelength (180 nm ~ 3.2 μm). The excitonic carrier generation was proposed for the ultraviolet excited photocurrent of the aromatic polymers used here (polyethylene terephthalate, polyethylene naphthalate, polyparaxylyrene, polystyrene and polycarbonate) from the experiments of the optical absorption and the photoluminescence. Photocarrier injections from metal electrodes were also observed in all polymers employed here (polyethlene, polyvinyl chloride, as well as the aromatic polymers). The study of photoinjections could give the contact barrier height and suggest the existence of surface states. Generally, electrons were more easily injected. In the visible and infrared wavelength range, the optical release of trapped electrons was observed. The photostimulated detrapping current (PS DC) analysis revealed that the molecular motion greatly contributed to the detrapping process. The carrier transport in polymers is considered to be composed of the inter- and intramolecualr transports. The molecular motion was also found to enhance the intermolecular carrier transport in polyethylene around the glass transition temperature. Also the photocurrent was found to be either bulk limited or electrode limited. In polyethylene terephthalate, space charge limited photocurrents were observed if excited with strongly absorbed light at high intensity, but at low intensity photocurrents deviated from the theoretical space charge limited characteristics.
