摘要： Method for marking a material, comprising including at least two components having different fluorescent characteristics as a blend of components in the material, the at least two components not being already associated with the material and at least one of the at least two different components having a fluorescence that varies in spectral position and/or intensity according to variation of pH, the at least two components being included in the material in an amount effective to be qualitatively and/or quantitatively determined. Also, provided are marked materials and methods of authenticating and preventing counterfeiting and dilution.
