FIELD: physics, optics.
SUBSTANCE: invention relates to means of labelling articles. The technical result is more secure labelling. The method is based on embedding quantum nanorods on track pores of polymer membranes and generating photo-induced luminescence anisotropy in the layer of nanorods. The method includes, in linearly polarised light, selective action of light of a certain wavelength on a portion of the nanorods, spatial orientation in a sample of which matches the direction of the electric field vector acting on the sample.
EFFECT: simple method of manufacture, broader technological approach and lower requirements for accuracy of monitoring parameters of hidden labels with polarisation contrast during manufacture thereof.
