摘要: Abstract Coumarin laser dyes have been shown to undergo efficient energy transfer when solubilized and co-bound poly(methacrylic acid (PMAA) in water at pH 3.0. Under these conditions are bound relative proximity (about 5.0 nm) within microdomains of the polymer its compact or hypercoloid form. Energy efficiencies as high 78% (assumed Forster dipole mechanism) measured from fluorescence data for coumarin pairs displaying a good overlap absorption emission spectra.
