FCC SIO2 MDMO-PPV METHOD FOR MANUFACTURING A THIN FILM CONSISTING OF A COLLOIDAL CRYSTAL INFILTRATED WITH THE LUMINESCENT MDMO-PPV POLYMER MADE OF SILICASIO2 SPHERES HAVING A FACE-CENTERED CUBIC SYSTEMFCC

摘要

The present invention relates to a process for the preparation of poly (2-methoxy-5-(3 ', 7'-dimethyloctyloxy)-1,4-phenylene-vinylene] (MDMO-PPV)₂ To a method for producing a thin film composed of spheres. The thin film may be deposited on a substrate of indium oxide (ITO) doped with soda lime or tin. The method comprises:₂ Synthesizing a colloidal solution and a high viscosity organic solvent at an exact ratio of the spheres, and then treating it by spin coating. By the above-described method, it is possible to obtain a film having a controllable thickness and a good structural quality which can be easily attached as an active region in an organic light emitting diode, and due to the film described here, the emission of light generated by the active region Can be significantly improved.;
