Outline of Final Research Achievements

We made a cermet thin film with Ag nano-particles in Alumina by using metal organic decomposition method for solar thermal utilization. The starting solvent with both metal organic material and metal nano-particles in controlled volume concentration is prepared for the cermet thin film fabrication. The spin-coated materials are annealed at 737K for 1 hour. The spectral absorptance of the sample was measured for the evaluation. The averaged absorptance in visible range was 0.9, and the averaged emittance in infrared range was 0.08. The measured results were agreed well with the analytical solution. We showed that the designed cermet can be made by low costs fabrication process with MOD method.
