Hexagonal pillar shaped ZnO nanorods with different sizes have been successfully synthesized by spray pyrolysis technique (SPT). The equal amount of methanol and water is used as a solvent to dissolve the AR grade Zinc acetate for precursor solution. This solution is sprayed on to the glass substrate heated at 350°C. The films were characterized by ultra-violet spectroscopy (UV), X-ray diffraction...
In this article, copper germanate (CuGeO3) mixed noble metal pervoskite oxide was prepared by solid-state synthesis process first time. XRD confirms the orthorhombic pervoskite phase of material. Thick films of CG were prepared by screen-printing technique. The gas sensing performance of thick films were tested for various gases. It showed maximum sensitivity to H2S gas at 50degC for less than 10ppm...
Strontium titanate (SrTiO3 (ST)) was prepared mechanochemically from Sr(OH)2 and TiO2. XRD confirms the pervoskite phase of material. Thick films of ST were prepared by screen-printing technique. The gas sensing performance of thick films were tested for various gases. It showed maximum sensitivity to CO gas at 350degC for 100 ppm gas concentration. To improve the sensitivity and selectivity of the...
