Sensitivity enhancement through doping
I've been reading the emulsion posts here with interest, trying to put together the complex picture in my mind. I ran across a paper by Belloni in 2003:
I'd be very interested in PE's comments as to how the sensitivity enhancements by HCO2- doping fit into the various ways to boost response (2-electron, etc.) or whether this is just another name for something already discussed somewhere in these vast posts. This technique looks like it works both by removing some of the photoholes which scavenge electrons, and creating a formyl radical which enhances the rate of silver ion reduction.
Of course, how practical this is as a technique is completely out of my comfort zone [my day job is space plasma physics].
