Issue Date: | 27-Aug-2015 | Publisher: | Soc. | Source: | Optics Express 19 (23): A1236-A1244 (2015) | Abstract (english): | We report on a band edge absorber/emitter design for high temperature applications based on an unstructured tungsten substrate and a monolayer of ceramic microspheres. The absorber was fabricated as a monolayer of ZrO2 microparticles on a tungsten layer with a HfO2 nanocoating. The band edge of the absorption is based on critically coupled microsphere resonances. It can be tuned from visible to near-infrared range by varying the diameter of the microparticles. The absorption properties were found to be stable up to 1000°C. |
