中文摘要：

A new solar selective absorbing coating of Mo/NiAlN/NiAlON/SiO2 multilayer was prepared on stainless steel（SS） substrates by magnetron sputtering for solar thermal power applications. The optical constants and thickness of individual layers were simulated using the Scout software based on the experimentally measured reflectance and transmittance spectra of individual layers. The coating of Mo/NiAlN/NiAlON/SiO2 with an ideal solar absorptance（α） of 0.945 in the solar spectrum range was designed via the optical constants of each layer in the Scout software. The Mo/NiAlN/NiAlON/SiO2 coating was deposited via the optimized layer thickness. A good spectral selectivity with absorptance（α=0.936） and emittance（ε=0.09, T=80 ℃） was obtained. This method, which incorporates the optical simulation with the related experiments, provides a convenient approach to obtain the ideal solar selective absorbing coatings.
