| Research Abstract |
To use the nanostructured metals for solar thermophotovoltaic system, the optical emittance of the material and the durability to high temperatures were investigated experimentally. It was found that the nanostructures were re-integrated to the surface when the surface temperature was sufficiently higher than 1000 K. Emittance became close to unity in wide wavelength range when the nanostructures were formed. When the nanostructures were slightly re-integrated to the surface, the emittance decreased in long wavelength rage with high emittance in near infrared range; the material could be more suitable for the emitter for the thermophotovoltaic system.
