  • Publication number: 20110292376
    Abstract: An apparatus and method for detecting Raman and photoluminescence spectra of a substance and identifying said substance by Raman and/or photoluminescence spectral characteristics of said substance are disclosed. An apparatus comprises a replaceable laser source aggregate with a laser source, a collimating system, a socket for receiving said replaceable laser source aggregate, while ensuring the operation of said apparatus with no further adjustment of a positioning of said collimating system or said laser source, a filtering system, a light dispersing system optimized for a spectral resolution and a spectral range sufficient to simultaneously obtain Raman and photoluminescence spectra of said substance, a detector, and at least one controller for processing electrical signals.

  • Publication number: 20110049239
    Abstract: A method for storing and coding information which utilizes mixtures of metal nanoclusters with dyes and other Raman-active substances is disclosed. A method for reading and decoding the stored information by measuring the Raman spectra is also disclosed. To code and store information, a plurality of dots or markers, each consisting of a mixture of two or more Raman-active substances taken in different proportions, is applied on a on object. The number of substances in the mixture and the relative quantities of each substance in the mixture carry the information to coded by each dot. By scanning a sequence of dots on the object, information stored in the sequence can be read and decrypted. Surface enhanced Raman scattering associated with metal nanoclusters and large Raman cross section of colored Raman-active substances make it more feasible to detect the Raman signal from a single dot of a small size (up to the diffraction limit) on the millisecond time scale.
