摘要：

TiO2/QDCdS heterostructure was synthesized by depositing preliminarily prepared cadmium sulphide (CdS) quantum dots onto microcrystalline rutile films and then their absorption and luminescence spectra were studied. It was observed that photon processing of the TiO2/QDCdS heterostructure with high-power light fluxes of xenon flash lamps contributes to the generation of the conditions necessary for the separation of nonequilibrium charge carriers.
