| contents | Photoluminescence properties of Al2O3:Eu thin films deposited by spray pyrolysis C. Falcony M. García A. E. Esparza García Física, Astronomía y Matemáticas Europuim (Eu) doped aluminum oxide (Al2O3) thin films were deposited on silicon and quartz substrates by spray pyrolysis technique, from a solution at 0.062 molar containing aluminum and europuim acetilacetonates. Eu-doping was obtained by adding to the solution the acetilacetonate in different concentrations. Structural, optical and morphological characteristics of the films, as a function of deposition conditions such as variation of the impurity concentration and deposition temperature are presented. In particular in relation to the optical characteristics (photoluminescence) of the films, it has been observed a characteristic emission associated with radiative transitions between the europium electronic energy levels. The overall spectra observed consist on several peaks associated with such transitions showing a red light emission. Structural characterization was performed by measurements of X-Ray diffraction patterns and morphological characterization by atomic force microscopy 1999 artículo científico 1665-3521 https://www.redalyc.org/articulo.oa?id=94200919 en http://www.redalyc.org/revista.oa?id=942 Superficies y vacío application/pdf Sociedad Mexicana de Ciencia y Tecnología de Superficies y Materiales A.C.
