Abstract:
Flash photolysis was used to study photobleaching of colloidal CdS particles with the controlled size. The rate constant of the photobleaching relaxation was found to depend on the size of the colloidal particles, an increase of the particle size resulting in a decrease of the rate constant. The influence of various electron acceptors on the photobleaching relaxation kinetics was investigated too. The addition of well adsorbing acceptor molecules decreases the initial amplitude of photobleaching and practically does not change the rate constant of the photobleaching relaxation. The photobleaching decay kinetics remains unchanged compared to the photobleaching relaxation kinetics of pure CdS. The addition of acceptor molecules with the small adsorption constant results in an increase of photobleaching relaxation rate constant, while the initial amplitude of photobleaching remains unchanged. Moreover, in the last case the photobleaching decay kinetics became exponential
