Abstract
Molybdenum trioxide MoO3 films with optical properties were successfully grown on wood substrates using a lowtemperature hydrothermal method Scanning electron microscopy analysis shows that MoO3 thin films were composed of rodslike microstructures and the rod sizes increased as the initial pH value of the solution increased Xray diffraction studies indicate crystallinity was greatly improved by increasing the pH value of the precursor solution Raman spectrum Xray photoelectron spectroscopy and Fourier transform infrared spectroscopy analysis further proves that pure MoO3 films could be grown on a wood substrate The UV–Vis analysis suggests that the films exhibited better in response to UV light The band gap energy estimated from the Kubelka–Munk function was found to be in the range of 2847–2974 eV The results from thermogravimetric analysis and differential scanning calorimetry experiments imply that the films possessed good thermal stability
