ABSTRACT:
A color-change material layer comprising: a color-change material that converts light of a second frequency range higher than a first frequency range to light of the first frequency range; and a transparent material having a refractive index of at least 1.6 intermixed with the color-change material, wherein the layer is substantially non-scattering to light of the first frequency range.
