Title: Enhanced invisible-fluorescent identification tags for materials

Abstract

A tag composition includes a naphthalocyanine tag component that is invisible in light of the visible spectrum and which emits fluorescent light in a non-visible spectrum under a non-visible excitation energy, a binder for binding the tag to a surface of a material; and a solvent, wherein the tag component and the binder are dissolved in the solvent.
