Abstract
A high temperature stable composition includes a first material and a second material interspersed within the first material so as to form a structure. The composition is structured such that the first and second materials maintain a periodicity of distribution between about 100 nm and about 1000 nm, and the composition is operable to reflect photons having a wavelength greater than about 700 nm and to emit or transmit photons having a wavelength between about 400 nm and about 700 nm at temperatures greater than about 2000 Kelvin for at least about 10 hours.
