Sintesi e caratterizzazione di nanoparticelle di ossido di stagno dopate

In the last years, new materials have been developed in the broad area of nanoscience. Among them, an emergent class characterized by excellent electrical conductivity properties as well as high optical transmittance in the visible region are TCOs (Transparent Conducting Oxides). Due to their versatile properties, they have found many applications in a lot of optoelectronic devices, such as solar cells, liquid crystal displays, touch-panel displays, gas sensors, to cite a few examples. Different research groups have studied and characterized the TCOs. In this context, a new synthetic method has been developed to produce FTO nanocrystals (Fluorine-doped Tin Oxide NCs) in Prof. Pinna’s lab at the Humboldt University in Berlin. FTO belongs to the TCO category, and they have been studied as a promising alternative to ITO NCs (Indium Tin Oxide) which represent the standard TCO material in terms of properties and performances. In this work, FTO NCs have been synthesized using the “benzyl alcohol route” (a non-aqueous sol-gel method) via microwave, which permits to produce FTO particles with good properties as revealed by the characterizations performed, employing a cheap, fast and clean method.
