α-MoO3 thin films prepared by spray pyrolysis

In this work thin films of molybdenum trioxide (MoO3) were prepared by the pyrolytic atomization technique. The films were deposited on glass substrates and obtained from a precursor solution of Tetrahydrate Ammonium Heptamolybdate ((NH3) 6Mo7O24.4H2O) 0.1 M. The substrate temperature was kept const...

Las películas fueron depositadas sobre sustratos de vidrio y obtenidas a partir de una solución precursora de Heptamolibdato de Amonio Tetrahidratado ((NH3)6Mo7O24.4H2O) 0.1 M. La temperatura del sustrato se mantuvo constante en 400 oC y se varío el volumen de la solución precursora. Las muestras se caracterizaron por difracción de Rayos X (XRD), espectroscopía infrarroja, Microscopía Electrónica de Barrido (SEM) y eléctricamente a través de medidas de resistividad eléctrica en función de la temperatura. Las muestras crecen con estructura cristalina correspondiente a la fase alfa del MoO3 con dirección preferencial de crecimiento a lo largo de los planos (0k0). Al aumentar el volumen de la solución precursora la superficie de las muestras se vuelve porosa. La resistividad en estas muestras cambia en un orden de magnitud cuando son expuestas a la atmosfera de CO.application/pdfspaUniversidad EAFIThttp://publicaciones.eafit.edu.co/index.php/ingciencia/article/view/431http://publicaciones.eafit.edu.co/index.php/ingciencia/article/view/431Copyright (c) 2011 H M Martínez, J Torres, L D López-Carreño, J E Alfonso, Luis Moreno, A PardoAcceso abiertohttp://purl.org/coar/access_right/c_abf2instname:Universidad EAFITreponame:Repositorio Institucional Universidad EAFITIngeniería y Ciencia; Vol 7, No 14 (2011)α-MoO3 thin films prepared by spray pyrolysisPelículas delgadas de α-MoO3 preparadas por atomización pirolíticaarticleinfo:eu-repo/semantics/articlepublishedVersioninfo:eu-repo/semantics/publishedVersionArtículohttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1Moo3Pyrolytic AtomizationCo SensorSemXrdMoo3Atomización PirolíticaSensor De CoSemXrdMartínez, H MTorres, JLópez-Carreño, L DAlfonso, J EMoreno, LuisPardo, AUniversidad Nacional de ColombiaIngeniería y Ciencia714105117ing.cienc.THUMBNAILminaitura-ig_Mesa de trabajo 1.jpgminaitura-ig_Mesa de trabajo 1.jpgimage/jpeg265796https://repository.eafit.edu.co/bitstreams/18a0137b-98b0-48e9-be7a-87232b209f1f/downloadda9b21a5c7e00c7f1127cef8e97035e0MD51ORIGINAL6.pdf6.pdfTexto completo PDFapplication/pdf550238https://repository.eafit.edu.co/bitstreams/88b26a74-95f1-4f3c-a507-52b409006c2d/download63ef073c15a31f6a63a0a6ad0951e5d5MD52articulo.htmlarticulo.htmlTexto completo HTMLtext/html373https://repository.eafit.edu.co/bitstreams/6758c6a7-5b45-4899-9fd4-c163c4d16725/download46d89764ab30d635802bf59bea6a4023MD5310784/14466oai:repository.eafit.edu.co:10784/144662020-03-02 22:11:29.223open.accesshttps://repository.eafit.edu.coRepositorio Institucional Universidad EAFITrepositorio@eafit.edu.co
