Metal oxides are presently employed in a number of advanced technological applications ranging from sensing, biology and energy. For such applications a good control of material properties ranging from morphological and structural to functional ones is required in order to improve or enhance the performances of the systems and the related devices. We here review our work on the Pulsed Laser Deposition of nanostructured films and surfaces showing that a fine tuning of morphology and structure can be achieved for metal oxides such as tungsten and titanium oxide. Starting from the control of the building units constituting the material we show that film morphology can be varied from compact to columnar and nanostructured to a hierarchical assembly of nanoparticles and finally to highly porous foam-like. Film structure can be varied from amorphous to nanocrystalline with the possibility to vary the oxide phase. Finally we will discuss possible applications showing that such oxides have good performances as functional materials.

Abstract
Metal oxides are presently employed in a number of advanced technological applications ranging from sensing, biology and energy. For such applications a good control of material properties ranging from morphological and structural to functional ones is required in order to improve or enhance the performances of the systems and the related devices. We here review our work on the Pulsed Laser Deposition of nanostructured films and surfaces showing that a fine tuning of morphology and structure can be achieved for metal oxides such as tungsten and titanium oxide. Starting from the control of the building units constituting the material we show that film morphology can be varied from compact to columnar and nanostructured to a hierarchical assembly of nanoparticles and finally to highly porous foam-like. Film structure can be varied from amorphous to nanocrystalline with the possibility to vary the oxide phase. Finally we will discuss possible applications showing that such oxides have good performances as functional materials.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
