The decay of sensitizer phosphorescence in a rigid solution modified by the electronic energy transfer by the mechanism of dipole-dipole interaction mixing with the dipole-quadrupole interaction is proposed. The rate constant for the transfer process is expressed as k(R)=………………………. Where τ=τo(1+α).
Calculations are made of the yield and the decay time of the sensitizer phosphorescence as function of the activator concentration and the mixing coefficient of dipole-dipole interaction with dipole-quadrupole interaction. It is hoped that the proposed mechanism will provide a sound, quantitative basis for analyzing experimental data in a triplet-singlet energy transfer process. As a demonstration, results indicate that about 9% of the electronic energy radiationlessly transferred from triplet triphenylene-d12 to singlet Rhodamine B is induced by the electric dipole-quadrupole coulombic interaction. - 英文摘要: --
