Semiconducting Nanocrystals Comprising a Metal Sulfide Shell and Methods for their Preparation
Methods for synthesizing a semiconductor nanocrystal are provided comprising providing a semiconductive core; providing a metal precursor solution comprising a metal acetate, a non-polar solvent, trioctylphosphine, and trioctylphosphine oxide; providing a sulfur precursor solution; admixing the semiconductive core, the metal precursor solution, and the sulfur precursor solution to form a reaction dispersion; and heating the reaction dispersion to a temperature sufficient to induce formation of a metal sulfide shell on the semiconductive core. Nanocrystals synthesized by these methods are also provided.
