Ag Based Photography

Reactions of photoelectrons with cation defects as described here have also been found for mercury halides or for oxalates of Fe and Pd. Lead halides, in contrast, possess mobile anions which can trap photoelectron holes. In this case, the absorption of photons leads immediately to a positive image, where the illuminated areas appear light.
