    Abstract: This patent disclosure describes novel compositions and methods used in the verification of products or documents based on the reading of emitted light from luminescent compositions that can be incorporated or applied to a wide variety of materials. Specifically, the compositions are uniquely luminescent at various wavelengths, displaying qualities of image, wavelength, and time scale for the measure of luminesce decay. The light emitted from the composition, and specifically, the measure of the variable and adjustable luminescence lifetimes provides a multi-parameter signature for purposes of comparative light decay analysis of verification marks or features.
