Abstract
Binary or ternary nanoparticles containing a group I metal, a group VI non-metal, and perhaps a group III, IV, or V non-metal are produced using a single or multiple source precursor. A precursor and a surfactant are mixed, a solvent is added to the mixture, the mixture is heated at a temperature close to the boiling point of the solvent for a desired amount of time, and the mixture is cooled. The nanoparticles are separated from the solvent by permitting the solvent to evaporate. The resulting nanoparticles may be used in photovoltaic and other semiconductor applications, imaging, biological applications, or in compositions.
