| abstract |
The present application provides a light-emissive nitride nanoparticle, for example a nanocrystal, having a photoluminescence quantum yield of at least 1%. The nanoparticle includes at least one capping agent provided on a surface of the nitride crystal and containing an electron-accepting group for passivating nitrogen atoms at the surface of the crystal, and an electron-donating group for passivating metal, boron or silicon at the surface of the crystal. Preferably, the nitride crystal is indium nitride and the capping agent is a zinc carboxylate. The invention also provides non-emissive nitride nanoparticles. |
