Abstract (en)
[origin: WO2010112788A2] The invention relates to a method for obtaining a structure with a textured external surface (25, 23, 24) intended for an organic light-emitting device, said structure including a mineral glass substrate (2) having a surface that is provided with protrusions (23') and cavities (24'). According to the method, an etching mask is deposited on the surface (21) of the substrate and the surface of the substrate is etched around the etching mask, followed by the removal of the mask. The invention is characterised in that one of the etching mask preparation steps comprises the formation of a multitude of nodules (60) arranged randomly on the surface of the substrate and formed by a material having no affinity for glass, and in that, following the etching step, the slopes of the protrusions having submicronic heights and widths are smoothed sufficiently to form the thus smoothed textured external surface.
