FIELD : chemistry. SUBSTANCE : method consists in formation of metal plasmon nanoparticles on the inorganic luminescent nanoparticles surface, where nanoparticles are previously doped by rare earth metal ions. Plasmon nanoparticles are prepared by reduction of liquid solutions. The colloidal solution of inorganic luminescent nanoparticles in 1.2-dichloroethane is mixed with a supramolecular complex solution [{Au10Ag12(C2Ph)20}Au3PPh2(C6H4)3PPh2)3][PF6]5 in 1, 2-dichloroethane to obtain a liquid solution, the liquid solution is recovered by laser radiation with a wavelength corresponding to the absorption band of the supramolecular complex, a power density of from 0.1 to 1 mW/cm2at laser exposure time of 10-60 minutes. EFFECT : invention enables high chemical purity of markers and small number of processing steps. 5 dwg, 3 ex
