摘要： A population of light-emissive nitride nanoparticles has a photoluminescence quantum yield of at least 10% and an emission spectrum having a full width at half maximum intensity (FWHM) of less than 100 nm. One suitable method of producing light-emissive nitride nanoparticles comprises a first stage of heating a reaction mixture consisting essentially of nanoparticle precursors in a solvent, the nanoparticle precursors including at least one metal-containing precursor and at least one first nitrogen-containing precursor, and maintaining the reaction mixture at a temperature to seed nanoparticle growth. It further comprises a second stage of adding at least one second nitrogen-containing precursor to the reaction mixture thereby to promote nanoparticle growth.
