摘要
FIELD: chemistry.;SUBSTANCE: invention can be used to ensure protection of valuable documents from falsification. Proposed is an optical accumulating luminophore based on a garnet structure, with a composition wherein Ln comprises at least one of La, Lu, Y; A comprises at least one of Ge, Sc, Si; Q comprises at least one of Ag, Cr, Hf, Mo, Nb, Sn, Ta, Ti, W, Zr; R comprises at least one of Bi, Pr, Nd, Sm, Eu, Tb, Dy, Ho, Er, Tm, Yb; T comprises at least one of B, F, Li, Mg, K, Na; 1.0≤х≤3,2 and 0≤у≤1.65, 0.5≤m≤5.2, 00.002 and 2.8≤x+y+p+r≤3.2. Unlike in the stoichiometric composition with an equalised charge of a gadolinium-aluminium garnet (Gd3)(Al5)O12, the elements Al, Ga, Ge, Sc, Si are present in the position of aluminium in a total amount different from the stoichiometric amount. Proposed are a method for verifying an authenticity indicator, an apparatus for implementation of the method, an authenticity indicator, and a valuable document.;EFFECT: inventions make it possible to ensure protection of valuable documents using an accumulating luminophore characterised by stability, fast readability, adapted reading spectrum and/or capability thereof of accumulating charge in the blue spectral range.;22 cl, 8 dwg, 10 tbl, 21 ex
