Abstract

The invention disclosed herein provides a quick, low-temperature method for production of highly luminescent, CdS/ZnS graded-shell passivated, CdSe-core-nanocrystal quantum dots. The method uses non-toxic, easy-to-handle cadmium, zinc and sulfur precursors. Quantum dots produced using the present method are suitable for bioimaging applications.
