The transfer of excitation energy from the excited solvent to the solute was studied as a function of solute concentration for solid solutions of anthracene and 9,10diphenylanthracene in polystyrene. Transfer efficiencies and fluorescence spectra were obtained for both systems. The fluorescent light pulse of both systems, when excited by electrons and u-v radiation, was recorded and analyzed. Results indicate that radiative transfer predominates at low solute concentration, while at higher solute concentration the transfer prccess is predominantly nonradiative. Differences between the two systems are probably due to anthracene being chemically bound to the polymer chain, whereas 9,10- diphenylanthracene is not. (auth)
