  • Raman-active taggants and thier recognition
    Publication number: 20040058058
    Abstract: An organic or organoelement, linear or branched, monomeric or polymeric composition of matter having a Raman-active component in the form of particles. The particles having a maximum dimension of 50 &mgr;m. The Raman-active compound is applied to a substrate. When the Raman-active compound is exposed to a laser light wavelength which is batochromically well beyond a spectral region of maximum absorbance of said Raman-active compound, Raman scattering can be detected.
    Type: Application
    Filed: June 4, 2003
    Publication date: March 25, 2004
    Inventors: Alexander Nikitovich Shchegolikhin, Olga Leonidovna Lazareva, Valery Pavlovich Mel'nikov, Vassili Yu Ozeretski, Lyle David Small
