In this study, a solar spectral selective absorbing coating of SS-(Fe3O4)/Mo/TiZrN/TiZrON/SiON exhibiting an absorptance of 0.95 and an emittance of 0.08 at 80 degrees C is reported. The structure and morphology of each layer were investigated by X-ray and Fourier transform infrared spectroscopic analyses. After heat treatment at 500 degrees C for 300 h in vacuum, the values of absorptance and emittance became 0.92 and 0.10 (at 80 degrees C), respectively. Moreover root mean square roughness of the coating measured by atomic force microscopy increased to 8.14 nm from 4.79 nm, indicating good thermal stability at 500 degrees C. (C) 2014 Elsevier B.V.
