Abstract
A chromic luminescent composition and method for fabricating the composition are disclosed. The chromic luminescent composition comprises at least one or more non-luminescent materials and one or more luminescent materials. The one or more non-luminescent materials having absorption spectra that at least partially overlap with the spectrum of incident electromagnetic radiation. The one or more luminescent materials convert at least a portion of energy of incident electromagnetic radiation to a lower energy wavelength. The one or more non-luminescent materials and the one or more luminescent materials are selected such that, when subsequently exposed to incident electromagnetic radiation, color and brightness are substantially modulated through absorption and emission as a function of incident electromagnetic radiation. Also disclosed are a chromic luminescent textile and a method for fabricating the textile.
