摘要：
The Sm2O3 powders were embedded into the pore of Cu microporous material to form a Sm2O3/Cu mosaic structure by solid state reaction at 900 degrees C for 1.5 h. The infrared optical properties and emissivity of the obtained structure were characterized. For the Sm2O3/Cu mosaic structure, the region of Sm2O3 could improve the absorption for infrared light of 1.06 mu m. The region of porous Cu has influence on the infrared emissivity of such mosaic structure. By adjusting the Cu content, the infrared emissivity could be tuned from 0.19 to 0.72 at 3-30 mu m. The prepared mosaic structure exhibits potential to act as a new kind of absorptive material with low emissivity to absorb the infrared light of 1.06 mu m. (C) 2012 Elsevier B.V. All rights reserved.
