Structural, optical and electrical characterization of hydrothermally synthesized V2O5-NiO nanocomposite thick films for NO2 sensing
In this work V2O5–NiO nanocomposites were synthesized by a hydrothermal method with varying V2O5 concentrations (0.1, 0.3, 0.5 and 0.7 N) and fabricated into thick films using screen printing. Structural analysis by XRD confirmed the cubic phase of NiO and orthorhombic V2O5, with crystallite size decreasing from 9.19 t...
