  • Publication number: 20120112224
    Abstract: A process for obtaining a structure having a textured external surface for an organic light-emitting device, which structure includes a mineral glass substrate having a surface which is provided with projections and depressions, the process including the deposition of an etching mask on the surface of the substrate and the etching of the surface of the substrate around the etching mask, and possible removal of the mask, wherein one of the steps of preparing the etching mask consists in forming a multitude of nodules randomly arranged on the surface of the substrate and made of a material possessing no affinity with the glass and wherein, after the etching step, the structure undergoes a moderating step in which the slopes of the projections of submicron height and width obtained by etching are moderated sufficiently to form the thus moderated textured external surface.

  • Patent number: 7348054
    Abstract: This substrate is coated with a composite film based on a mesoporous mineral layer containing nanoparticles formed in situ inside the layer. The composite film has a periodic lattice structure over a major portion of the thickness in which the nanoparticles are present, in which structure the nanoparticles are arranged in a periodic manner on the scale of domains of at least 4 periods in the thickness of the film. This structure can be obtained from a mesoporous mineral layer of periodic structure on the scale of domains of at least 4 periods of pores, forming a matrix on the substrate, by: depositing at least one precursor in the pores of the matrix layer; and growing particles derived from the precursor with the spatial distribution and the dimensions being controlled by the structure of the pores of the matrix. Applications to materials for electronics, nonlinear optics and magnetism.
