Theory of Spectral Sensitization

Paper presented at a Symposium on “Fundamental Problems in Photographic Science” organized by the Science Committee of The Royal Photographic Society on 8-10 September 1975, in Oxford, England.

Abstract

A brief treatment is given of the physical basis for models of spectral sensitization. Models now current are examined; recent measurements of surface potential of sensitized and unsensitized surfaces are not consistent with the predictions of models of the “Fermi level” type. Dynamical electron transfer models incorporating the statistical character of ionization energies seem to have the best potential as tools for investigating phenomena associated with spectral sensitization.
