Method for manufacturing nanocrystalline luminophores to record information and method for reading the information

摘要

A marker for protection valuable liquid and solid materials comprising organic or nonoraganic liquid solvents as dispersed medium, surface active substances on nanomaker, characterized in that nanomarker is a homogeneous mixture of two or more different nanoluminophors, favourable chosen from metals, nanocrystalline metal oxides -A2O3, -granates-A3B5O12, per-ovskites-AB03, spinels-AB2O4 or stoichiometric compounds with large concentrations of optically active ions like fluorides, oxy-chlorides and others.
