Abstract
A nanoparticle having a core/shell structure can be rapidly and reproducibly prepared by the inventive method which comprises: (i) dissolving a shell precursor in a solvent to form a shell precursor solution, and then allowing the shell precursor solution to be stabilized at a temperature suitable for the shell precursor to form an overcoat on the surface of a core nanoparticle; and (ii) adding a powder form of the core nanoparticle to the stabilized shell precursor solution.

A method for preparing a nanoparticle having a core/shell structure which comprises:
- (i) preparing a core nanoparticle of a powder form;
- (ii) dissolving a shell precursor in a solvent to form a shell precursor solution:
- (iii) heating the shell precursor solution at a temperature sufficiently high to stabilize the shell precursor solution;
- (iv) adding the powder form of the core nanoparticle into the stabilized shell precursor solution:
- (v) maintaining the temperature of the solution for a time period sufficient to form an overcoat on the surface of the core nanoparticle;
- (vi) monitoring the growth of the overcoat being formed on the surface of the core nanoparticle;
- and
- (vii) cooling the solution to terminate the growth of the shell overcoat.
