Fabrication of planar iron oxide nanocomposite films and investigation of their optical and magnetic properties

摘要

Iron oxide nanoparticles and polymer planar films with different number of layers of iron oxide nanoparticles have been fabricated by the layer-by-layer alternating adsorption technique. It was established that the thickness of the PAH/iron oxide film and its refractive index increases with the increase of the layer number. The microwave irradiation affects the thickness of the PAH/iron oxide film and their refractive index. The increase of refractive index and decrease of thickness of nanocomposite films were observed. The electronic paramagnetic resonance (EPR) spectra of planar films were measured. It was found that parameters of the EPR spectra are sensitive to the number of nanoparticles layers.
