Abstract

The promising results obtained with the MAPLE-deposition of nanostructured thin films, to be used in different fields, are reviewed. Nanoparticles (TiO2, SnO2, CdS) and nanorods (TiO2) with well defined dimensions were suspended in appropriate solvents (distilled water, toluene) with low concentration (1wt% or less). The solutions were flash frozen at the liquid nitrogen temperature to form the targets to be laser irradiated. The MAPLE process allowed a successful transfer from the target to rough and flat substrates, preserving the starting composition and crystalline phase of the nanostructures in a wide range of experimental conditions. In contrast, a careful choice of the laser fluence is mandatory to avoid shape modifications. Growth of metal nanoparticles with a low dispersion in size was also obtained by the MAPLE technique, starting from target solutions of a metallorganic element (AcPd) diluted in different solvents (acetone, diethyl ether). It seems that selecting the solvent with appropriate values of viscosity and boiling temperatures, it is possible to modulate the nanoparticles size. Most of the deposited nanostructured films were tested as sensing elements for gas sensors.
