An optical element is provided. The optical element may comprise a material, the material being a matrix and a set of particles included in the matrix, the material having a molar fraction of SiOhigher than or equal to 65 percent, each particle having a dimension smaller than or equal to 80 nanometers.

Optical element and associated manufacturing method

The present invention relates to novel vitroceramic or lens compositions that are nanostructured and transparent or translucent, including at least 97%, such as 97% to 100%, preferably 99% to 100%, by weight, relative to the total weight of the material, of a composition having the following formula I: (GeO)(SiO)(BO)(GaO)(Oxy)(Oxy)(I) where Oxyis an oxide selected from ZnO, MgO, NbO, WO, NiO, SnO, TiO, BiO, AgO, CaO, MnO, or a mixture thereof, selected preferably from ZnO, MgO, NbO, WO, NiO, SnO, AgO, CaO, MnO, or a mixture thereof, selected more preferably from ZnO, MgO, AgO, BiO, NbO, Or a mixture thereof, selected most preferably from ZnO, MgO, AgO, NbO, or a mixture thereof, and Oxyis an oxide selected from NaO, KO or a mixture thereof, Oxyis preferably NaO, and x, y, z, a, b and k are as defined in claim, to the manufacturing method thereof and to the uses thereof in the field of optics.
