Photodeposition of Pt on Colloidal CdS and CdSe/CdS Semiconductor Nanostructures

Pt nanoparticles are deposited photochemically on the surfaces of colloidal CdS nanorods and CdSe/CdS nanoheterostructures. While Pt deposits at varying positions along CdS nanorods, the deposition on CdSe/CdS occurs preferentially near the CdSe core.
