Description
Summary:Molybdenum trioxide （MOO3）, thin films have been deposited on glass substrates by spin-coating method using ammonium heptamolybdate tetrahydrate （（NH4）6Mo7O24·4H2O） as a single source precursor of Mo and O. They were subjected to atmospheric heat treatment at different temperatures （200, 400 and 500 ℃）. MoQ thin films obtained were characterized using X-ray diffraction techniques （XRD）, scanning electron microscopy （SEM）, energy dispersed spectroscopy （EDS） and integrating sphere. The XRD patterns of annealed films show the formation of MoO3 in a polycrystalline phase, formation of MoO3 was also confirmed by EDS. The SEM photographs show that the thin films obtained are in layer-type structure and their grains size increases with increasing of annealing temperatures. The measurement results of integrating sphere show that the MoO3 thin film prepared at 500 ~C transmit about 72% and reflect about 12% of the visible spectrum.
