摘要： The present application provides nitride semiconductor nanoparticles, for example nanocrystals, made from a new composition of matter in the form of a novel compound semiconductor family of the type group II-III-N, for example ZnGaN, ZnInN, ZnInGaN, ZnAlN, ZnAlGaN, ZnAlInN and ZnAlGaInN. This type of compound semiconductor nanocrystal is not previously known in the prior art. The invention also discloses II-N semiconductor nanocrystals, for example ZnN nanocrystals, which are a subgroup of the group II-III-N semiconductor nanocrystals. The composition and size of the new and novel II-III-N compound semiconductor nanocrystals can be controlled in order to tailor their band-gap and light emission properties. Efficient light emission in the ultraviolet-visible-infrared wavelength range is demonstrated. The products of this invention are useful as constituents of optoelectronic devices such as solar cells, light emitting diodes, laser diodes and as a light emitting phosphor material for LEDs and emissive EL displays.

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.

摘要： A display comprises a light source and an image display panel disposed in an optical path from the light source. The light source comprises a primary light source for illuminating a re-emission material which comprises at least a first nanophosphor material for, when illuminated by light from the primary light source, re-emitting light in a first wavelength range different from the emission wavelength range of the primary light source. The image display panel comprises a first filter having a first narrow passband or a first narrow absorption band, the first narrow passband or first narrow absorption band being aligned or substantially aligned with the first wavelength range. The combination of a narrow wavelength range emitted by the first nanophosphor material and the narrow passband or narrow absorption band of the filter allows a display with high efficiency and a high NTSC ratio to be obtained.
