Henry Alberto MÉNDEZ PINZÓN has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method for manufacturing a thin film consisting of a colloidal crystal infiltrated with the luminescent MDMO-PPV polymer made of silica (SiO) spheres, having a face-centered cubic system (FCC)
    Patent number: 9859497
    Abstract: 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.
