摘要： A method of forming a nanoparticle can include admixing an aqueous solution into an oil-phase to thereby form an emulsion of droplets of the aqueous solution in the oil phase, the aqueous solution comprising a nanostructure precursor and a polymer, adding a silane precursor and catalyst to form a silica shell around each of the droplets to nanoreactors; annealing at a first temperature below the decomposition temperature of the polymer to aggregate the nanostructure precursor within the nanoreactor; and annealing at a second temperature above the decomposition temperature of the polymer to convert the aggregated nanostructure precursor to the nanostructure and decompose the polymer.

摘要： Disclosed herein are methods for forming one or more nanoparticles. The methods include depositing a solution comprising a block copolymer and a metal salt into one or more square pyramidal nanoholes formed in a substrate, and annealing the substrate to provide a single nanoparticle in each of the one or more square pyramidal nanoholes.
