Abstract

We have been studying the photocarrier generation mechanism in layered organic photoreceptors comprised of bisazo pigment based carrier generation materials (CGMs) and carrier transport materials (CTMs) using thermally stimulated current (TSC) technique. And it was concluded that the formation yield of initial ion-pair −(CGM-/CTM+) mainly determined the photosensitivity. It is known that the carrier generation yield is greatly enhanced by the coexistent CTMs in this type of photoreceptors. In the present study, we examine the primary process just after photoexcitation by means of time-resolved fluorescence spectroscopy. We observed that the CTMs considerably shortened the lifetime of CGM exciton. We attempt to correlate the quenching rate of CGM fluorescence by CTMs with the sensitivity of the photoreceptors.
