Title (EN) NANOSTRUCTURES FOR STRUCTURAL COLOURING
(FR) NANOSTRUCTURES POUR COLORATION STRUCTURELLE
Abstract: front page image
(EN)The invention relates to a nanostructured product with a structurally coloured surface. The nanostructured product includes a substrate with a nanostructured surface having nano-sized pillars or holes arranged in a periodic pattern and extending into or out from the substrate. The bottoms of the nano-sized holes or the tops of nano-sized pillars are provided with metal layers electrically isolated and distanced from a base surface of the nanostructured surface. A transparent or translucent protective layer covers the substrate and the metal layers.
(FR)La présente invention concerne un produit nanostructuré ayant une surface structurellement colorée. Le produit nanostructuré comprend un substrat ayant une surface nanostructurée ayant des piliers ou des trous de dimension nanoscopique agencés en un motif périodique et s'étendant dans et hors du substrat. Les fonds des trous de dimension nanoscopique ou les sommets des piliers de dimension nanoscopique sont pourvus des couches métalliques électriquement isolées et à distance d'une surface de base de la surface nanostructurée. Une couche protectrice transparente ou translucide recouvre le substrat et les couches métalliques.
