Abstract

Time-resolved depolarization measurements in the one-component rhodamine 6G system were used to probe the morphology of the effective surface available for dye molecules adsorption on porous silica. The migration of electronic excitation among the molecules was analyzed in terms of effective fractal dimension D of the adsorbed molecules. D increases gradually when the average pore size decreases. This finding is in accord with our previous studies on one-step electronic energy transfer.
