| 简介 |
PURPOSE : A gadolinium oxide insulating film is provided to ensure high dielectric constant and high transmissivity in a visible light region and to lower leakage current, thereby enabling the application to a light emitting electronic materials using a light emitting spectrum expressed by different rare earth elements.CONSTITUTION : A gadolinium oxide(Gd2O3) insulating film includes different rare earth elements and polyvinylpyrrol. A method for preparing the gadolinium oxide insulating film comprises the steps of : preparing a first solution by dissolving a gadolinium precursor and different rare earth elements in an organic solvent; preparing a second solution by adding polyvinylpyrrole and distilled water to the first solution and reacting the mixture; spin coating the second solution in a material to be coated; and forming a film by heat-treating the material to be coated.COPYRIGHT KIPO 2012 |
