Abstract

Novel highly luminescent Cu⁺ doped CdS quantum dots (QDs) were directly synthesized in aqueous phase through a facile single-step noninjection method. Due to their bright red fluorescence, ultrasmall size, and good biocompatibility, as-prepared CdS:Cu⁺ QDs have potential as probes in bio-imaging.
