Using Radio-Frequency reactive sputtering techniques, thin films of thermochromic vanadium dioxide (presenting a insulator-metal phase transition at Tc = 68°C) were covered by a cerium dioxide layer. Cerium dioxide was chosen for its chemical stability, infrared optical transparency and strong optical absorption in the ultrafiolet range. Vanadium dioxide was first deposited on a silica substrate by Radio Frequency reactive sputtering. Then, a ceria thin film was deposited on the vanadium dioxide film by the same technique. The bilayers were characterized by X-ray diffraction measurements, scanning electron microscopy, transmission electron microscopy and ellipsometry techniques. Optical properties were studied by infrared spectroscopy. The optical properties of these bilayers are similar to optical properties observed for non-coated pure vanadium dioxide films.
