    摘要: The invention relates to a security element for value or security documents comprising markers made up of a plurality of nanoparticles of at least two types, wherein a first type is a hollow nanoparticle provided therein with at least another nanoparticle of a second type having smaller dimensions. The markers thus simultaneously meet the geometric, particularly surface, and physicochemical conditions necessary for their detection.
