Abstract
The efficiency of carrier generation by the zerographic discharge technique has been measured on four films; a molecularly C60-doped polymer film, a molecularly C70-doped polymer film, an aggregate C60 film, and an aggregate C70 film. The yield for molecularly C70-doped polymer was three orders of magnitude larger than that for the film of molecularly C60-doped polymer. The photon energy dependence of efficiency for the aggregate films differed from that for the molecularly doped polymer films. The carrier generation efficiency spectrum for the aggregate films showed peaks corresponding to the Frenkel type excitons. The sensitivity of a photoreceptor fabricated with C70 was 0.5(cm2/(mu) J) at wavelengths in the 420nm-670nm region.
