Comparative analysis of TiO2 layers grown by pulsed laser deposition at atmospheric pressure and pyrolitic nebulization

espanolLas nanocapas ceramicas son ampliamente estudiadas por su interes en aplicaciones tecnologicas. Estos recubrimientos pueden conformar celdas solares, superficies de transmision, emision o reflexion selectiva de luz, entre otras tantas aplicaciones. En este trabajo se presenta una comparacion entre peliculas delgadas de TiO₂ depositadas por ablacion laser pulsado (PLD) y por nebulizacion pirolitica (sol-gel spray-pyrolisis, SP). La caracterizacion de las nanocapas se realizo empleando diversas tecnicas como microscopia electronica de barrido (SEM), espectrometria de dispersion de energia de Rayos X (EDS), microscopia de Fuerza Atomica (AFM), Difraccion de Rayos X y espectroscopia Raman. EnglishTiO₂ layers and nanolayers are widely studied due to its technological applications. This material could be used in solar cells, transmission, emission or selective reflection, among other applications. In this paper, we show a characterization of layers of TiO₂ grown by two different methods, Pulsed Laser Deposition (PLD) at atmospheric pressure and spray pyrolysis (SP). The samples were characterized by SEM, EDS, AFM, XRD and Raman Spectrometry.
