A method to enhance the reflectance of the artificial opal is demonstrated by coating Ag nanoparticles on the polymethylmethacrylate microspheres to form a metallodielectric artificial opal. The authors studied the angle-resolved reflection spectra of the metallodielectric opals. By a suitable coating of Ag nanoparticles on the microspheres, the reflectance of the opals is enhanced without changing the reflection wavelength. This metallodielectric material can be used as the high reflectance mirror.
