Co Precipitation

The water-soluble ZnSe:Ag quantum dots were synthesized in aqueous medium by chemical co-precipitation method with L-cysteine as surface modifier. The crystal structure and optical properties of the obtained ZnSe:Ag quantum dots have been characterized by X-ray power diffraction, infrared spectrum, UV-Vis absorption spectrum and photoluminescence spectrum. Results indicate that ZnSe:Ag quantum dots belong to the cubic blende structure and have good fluorescent characteristics. The L-cysteine modified on the surface of ZnSe:Ag quantum dots renders the quantum dots water-soluble, biocompatible.
