Formate as a Sensitivity Enhancer of Holographic Emulsions

Description

This paper reports experiments that confirm Belloni (2003) that pre-soaking a silver halide holographic emulsion in a dilute solution of the formate ion (HCO2-) will hypersensitize the emulsion by a factor of 5xs to 10xs, depending on the timing of development post-exposure. The quantum efficiency of the emulsion is effectively 1 in the first case. The extremely fine grain size of the holographic emulsion (Slavich PFG-01) is maintained and holographic image quality is excellent. When combined with a TEA pre-soak the expected TEA color shift is maintained.
