Nano-structured surfaces allow obtaining of colored gonio-apparent effects when the nano-structures dimensions are of the order of the visible spectrum wavelengths. these colors are usually modeled by means of the interactions type so-called « interferences type » ou « photonic crystals type » between the luminous radiation and a model structure. in this thesis, the anodization of aluminum substrates is used to produce surface structures at the submicron scale. this technique is industrially mature and allows to structure large surfaces. color effects were observed even if obtained structures are not perfectly ordered. the aim of this thesis is the understanding of the optical phenomena involved in the production of such effects. this man...
