Abstract

A chromic luminescent object comprising one or more chromic luminescent compositions incorporated into or onto one or more portions of the object, in which the one or more chromic luminescent compositions are selected such that, when subsequently exposed to incident electromagnetic radiation, at least brightness of the one or more portions of the object is substantially modulated through absorption and emission as a function of incident electromagnetic radiation is disclosed. Also disclosed are methods for fabricating the chromic luminescent object.
