Fluorescent CdS Quantum Dots: Synthesis, Characterization, Mechanism and Interaction with Gold Nanoparticles.
CdS quantum dot (QD) is a typical kind of II-IV nanoparticles, which plays an important role in the common type of core-shell QDs. It is of great practical significance to synthesize the water-soluble CdS QDs used in multicolor biomarkers and prepare core-shell QDs. In our case, we came up with a novel green method to manufacture CdS QDs with high quality, different size, and adopted UV-vis absorption, fluorescence, FTIR, XPS, HRTEM, SAED and STEM-EDX to discuss their growth mechanism. We successfully constructed fluorescence resonance energy transfer (FRET) system between CdS QDs and gold nanoparticles (AuNPs), then comprehensively and systematically studied the interaction between them.
