摘要： Disclosed are security articles and methods and systems for authenticating security articles through the application if temperature related stimuli. Carefully synthesized nanostructures are formed to exhibit a large number of defect states within the bulk of the nanostructure. The large number of surface defects create a plurality of electron trap states below the conduction band of the composition and/or a plurality of hole states above the valance band such that excitations are induced by small changes in energy at or around kT. In this manner, a security article formed using the synthesized nanostructures produces measurable changes in spectral output based on small changes in temperature at or about room temperature. This allows the security article to be verified at high speeds with low power requirements for induced temperature change.
