WebThe basic mechanism by which this happens was first proposed by R W Gurney and N F Mott in 1938. The incoming photon liberates an electron, called a photoelectron, from a silver halide crystal. Photoelectrons migrate to a shallow electron trap site (a sensitivity site), where the electrons reduce silver ions to form a metallic silver speck. WebMott and Gurney's book on electrons in ionic crystals, of which the second edition is now available, is an excellent and perhaps the first monograph on what might be called …
