摘要

FIELD: chemistry.;SUBSTANCE: luminescent protective ink contains a solvent and semiconductor nanocrystals dispersed in an organosilicon compound, consisting of successively arranged: semiconductor nucleus 1, first 2 and second 3 semiconductor layers and an outer 4 layer, the material of which is selected from an organosilicon polymer from a series which includes poly(aminoethyl)trimethoxysilane, poly(methacryl)triethoxysilane, poly(methyl) triethoxysilane, poly(mercaptoethyl) triethoxysilane, methyl-phenyl polysiloxane, polyethoxysilane. The semiconductor nanocrystals emit a fluorescent signal in a fluorescence wavelength range of 400-3000 nm under the effect of a visible or UV light source; the relative fluorescence quantum efficiency is at least 80%.;EFFECT: making a protective mark from luminescent protective ink, through which an article can be verified using simple means, providing further protection for twenty years.;13 cl, 4 dwg, 7 ex
