Materials for a photo-induced memory effect on charge-acceptance were investigated in
Polyvinylcarbazole (PVK) films and the film doped with triphenylmethane dyes on In2O3--SnO2 (ITO) conductive substrate exhibited an outstanding memory effect.
The photo-and spectral sensitivities, sensitization procedure, stability and erase of the memory effect were demonstrated in the photoreceptor consisting of PVK, 3, 3'-di (N-ethylcarbazoyl) phenyl carbonium tetrafluoroborate, and polyester on the ITO substrate.
The photoreceptor showed a high photo-sensitivity at 630nm and successfully applied to He-Ne laser recording.
