>Can one detect chemiluminescence with a PhosphorImager?
The answer is no (in general). These are two slightly different
phenomena - chemiluminescence and phosphorescence luminescence.
Although both involve the emission of light when an electron returns from
an excited or high energy state to a lower energy level the phosphor in a
phosphorimager requires radiation to cause excitation and
chemiluminescent light cannot excite it. However, I've heard that one
company (I think Biorad) makes a casette that can be excited by
chemiluminescence but I've heard that it does not work too well. So,
we're stuck with doing multiple exposures on Xray film for now.
