N2 - he present invention relates to a method for manufacturing thin films consisting of SiO2 spheres of 250 nm in diameter, packed in a simple cubic structure and infiltrated with the organic luminescent polymer Poly[2-methoxy-5-(3′,7′-dimethyloctyloxy)-1,4-phenylene-vinylene] (MDMO-PPV). The thin film can be deposited onto a substrate of soda lime or indium oxide doped with tin (ITO). The manufacturing method includes the synthesis of a colloidal solution with the correct proportions of SiO2 spheres and a high-viscosity organic solvent and the subsequent treatment thereof by spin coating. The provided method makes it possible to obtain films having a controllable thickness and a good structural quality that can easily be attached as an active region in an organic light-emitting diode where, due to the film described herein, the emission of light produced by the active region is considerably improved.
