Here, we propose a mono-material concept in which the required refractive-index contrast is generated within a single material through a multilayer stack of porous and dense microstructured titanium dioxide (TiO2). A key challenge in such architectures is the deposition of dense layers on porous ones without intermixing or excessive roughness. To address this, titanate 2D nanosheets are introduced as an interfacial layer. To demonstrate this concept, a Vis–NIR optical filter was designed using optical simulations and experimentally realized. The desired refractive-index contrast was achieved by tuning the porosity of consecutive amorphous TiO2 layers, with ∼1nm crystalline Ti0.87O2 titanate nanosheet interlayers enabling sequential stacking of dense and porous TiO2. This approach enabled the fabrication of a six-layer mono-material optical filter and establishes a sustainable strategy for designing versatile mono-material optical coatings.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"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
