Ion Optics created an array of regularly spaced holes in a thin conductive surface film on a dielectric substrate. When heated, this pattern behaved as a selective emitter, with more than 50% of total radiation in a well-defined peak with a center frequency determined by geometrical spacing. Peak wavelength did not alter with change in temperature, and materials easily survived 10 hours at 1000 C in air. The selective emitter will increase efficiency of thermophotovoltaic power converters
