Photoconductive Sensitivity and Trap Depths of the Sublimated Dye Films

Abstract

This investigation is concerned with a photoconductive sensitivity and the trap depths for sublimated dye films (SDF) in the spectral sensitization process. We have observed the photoconductive sensitivity (I_p/I_d in the range of 0.5-0.02 for SDK in a vacuum by their absorption of light. In addition, traps were observed for all types of sensitizing and desensitizing dyes.

We conclude that a small photoconductive sensitivity exists in these dyes and that several types of traps are associated with the spectral sensitization process. It would be expected to get a large photoconductive amplification since a large number of carriers are injected from the excited stale of solid slate dye into the conduction hand of photoconductor.
