Titanium oxide films were prepared on ITO coated glass substrates at 350 C using titanium (IV) isopropoxide, acetylacetonate and absolute ethanol as precursors by spray pyrolysis technique. The prepared films were characterized by X-ray diffraction, Scanning electron microscope, Fourier transform infrared spectroscopy and Energy dispersive analysis of X-rays. Estimated optical and electrical parameters...
The nAg/PVP and nAg/PVA composites were synthesized by using chemical reduction method. The neat Poly vinyl pyrrolidone (PVP) and polyvinyl alcohol (PVA) at different concentrations and their nano metal polymer composites were studied for electrical humidity sensing, ranging from 5–90% RH. The neat polymers and their composites were coated on ceramic rods having built in electrodes by drop casting...
In this work, the annealing effects of e-beam deposited Ta2O5 films on the pH sensitivities of EIS based sensors are presented. XPS studies confirmed that the films annealed above 700 °C showed the best stoichiometry (Ta1.96O5.04) compared to the as deposited film and the films annealed till 600 °C. XRD spectra confirmed the amorphous nature of the as deposited film, which remained amorphous till...
