PREPARATION AND CHARACTERIZATION OF LANGMUIR-BLODGETT-FILMS CONTAINING FULLERENE

Langmuir-Blodgett films containing a mixture of fullerene (C60) and ar achidic acid (C20H40O2) were deposited on three different substrates ( glass, quartz and silicon). The details of the dipping procedure are e xplained for three different values of the monolayer pressure. Optical studies in air at room temperature on films of various thicknesses de posited on quartz substrates were performed. From transmittivity and r eflectivity measurements the refractive index n and extinction coeffic ient k have been evaluated in the UV-visible spectral range. Finally, a preliminary structural analysis carried out by means of scanning ele ctron microscopy has shown that the films are homogeneous with some is olated cracks.
