Selective thermal emitters are materials which emit in narrow wavelength bands, unlike blackbody emitters which emit uniformly over all wavelengths. Materials with tailored emission/absorption characteristics can be useful for applications in energy conversion, energy conservation, chemical, and bio-chemical sensing. In this paper, we show that thin films of polar dielectric materials can act as selective emitters in two frequency bands on either side of the restrahlen band(s) of the polar… CONTINUE READING
