Thin films of molybdenum oxide (MoO3) doped cuprous oxide (Cu2O) was fabricated on soda lime glass substrated by casting coating technology. Hexagonal molybdenum oxide (h-MoO3) was synthesized by a solution based precipitation technique. Analysis by X-ray diffraction (XRD) confirmed that the as-synthesized powder had a metastable hexagonal structure. Scanning electron microscopy (SEM) images clearly depicted the morphology and size of h-MoO3. The morphology study had showed that the product enclose hexagonal rods. From the color measurement, the result of the color changes properties showed that 100% MoO3 was white colored changed to a blue color and the 1% Cu2O doped MoO3 was light brown colored changed to a light blue color when they all were exposed to UV irradiation. The optical band gap energy was estimated from the Kubelka–Munk (K–M) function and was found in range 2.25-3.15 eV. It has shown that this convenient and efficient approach could be applied in the mass-production of functional powders and films materials.
