Smart Color Designs with Ag and Au Metal-Island Films

Multilayer structures incorporating silver and gold metal-island films in two different embedding materials are designed to achieve the reflectance of three distinct colors. The designs are specially adjusted for micro and nanoarray fabrication to involve the least number of deposition runs. The designs were generated taking into account feasibility restrictions. However, it was found that color combinations are reduced, i.e., not all the combinations can be obtained using the investigated approach and the materials used.
