Many papers about plasmonic color using aluminum were reported recently. Experimental methods were usually top-down ways and the metal nano strucutre was on a substrate. There is no papers which samples were powder and fabricated by self-assembly method. Then we fabricated such a sample by vapor deposition to glass flakes and anealing. As a result of that, some colored specular were appeaerd after anealing. Observations of the structure, optical measurement and similation by FDTD were conducted.
