Abstract

Abstract: The relations between time dependent SERSintensity and fractional dimension of colloidal fractional aggregates formed in both the diffusion and the reaction limited regimes were established in the paper.According to the relationship, the fractional dimensions of silver bromide colloid aggregates formed in the two regimes were given by the time dependent SERSintensity of adsorbed pyridine in AgBr sol, they are in good agreement with the universal value and suggest that SERSwill be a useful tool in the study of kinetics of colloid aggregation, especially in the study of fractional structure of colloidal aggregates.

Key words: Colloidal aggregation.Fractional dimension, Surface enhanced Raman scattering(SERS)
