Luminescent nitride nanoparticles, eg, nanocrystals, having a glitter quantum yield of at least 1%. This quantum yield is much higher than conventional nitride nanoparticles. Conventional nitride nanoparticles have only weak radiation, and it is difficult to control the size of the produced nanoparticles. [Solution] Nitride nanoparticles are luminescent nanoparticles comprising a capping agent comprising an electron withdrawing functional group and a capping agent comprising an electron donating functional group, having a glitter quantum yield of at least 1%, and the nitride nanoparticle Is a metal nitride nanoparticle of Group III metal, and the capping agent containing an electron withdrawing functional group is zinc amide, carboxylate, acetoacetonate, sulfonate, phosphonate, thiocarbamate Alternatively, the capping agent that is a thiolate and contains an electron donating functional group is a phosphine, phosphine oxide, carboxylic acid, carboxylate, amine, sulfonate, ester, thiol or thiolate.
