FIELD: nanotechnologies.
SUBSTANCE: invention can be used in devices or materials for light generation, printing or marking. Luminescent nanoparticles include nucleus, obtained from luminescent metal salt, selectedfrom phosphates, sulphates or fluorides, which is surrounded by envelope, obtained from salt or metal oxide, which can prevent or reduce transfer of energy from nucleus after its electronic excitation to surface of nanoparticle. In order to obtain luminescent nanoparticles, according to invention first mixture, which contains nanoparticles of optionally alloyed luminescent sulphate, phosphate or fluoride of metal in organic medium is obtained. After that obtained mixture is subjected to interaction with source of anions for formed envelope and second mixture, which contains envelope-forming metal ions and organic complex-former, at 50-350 °C.
EFFECT: quantum output increase.
