Abstract

Methods for synthesizing luminescent nanoparticles and nanoparticles prepared by such methods are provided. The nanoparticles are prepared by a method in which an additive is included in the reaction mixture. The additive may be a Group 2 element, a Group 12 element, a Group 13 element, a Group 14 element, a Group 15 element, or a Group 16 element. In additions, a luminescent nanoparticle is provided that comprises a semiconductive core surrounded by an inorganic shell, an interfacial region and an additive present in the interfacial region or both the interfacial region and the shell.
