Abstract:
The current study present the preparation of NiO thick film sensors by using screen printing technique on glass substrate and study influence of annealing on electrical and optical properties of prepared thick films. Prepared films were annealed at in the range of 250°C to at 400°C using muffle furnace for 2 hours. Electrical properties of NiO thick film sensors were studied using resistivity, temperature coefficient ratio, and activation energy and optical properties were studied using FTIR and UV spectroscopy. It has been found that the resistivity of all prepared NiO thick film sensor decreased as annealing temperature increased. The energy band gap (Eg) of un-annealed and annealed at 250, 300, 350 and 400 °C NiO thick film sensors was found to be 3.25, 2.99, 2.81, 2.73, and 2.49 eV respectively. The change in optical band gap energy, reveals the impact of annealing on optical properties of the NiO films.
