Low-cost Fabrication of Cu doped ZnO (Zn_0.95Cu_0.05O) Film for Enhanced Gas Sensing Applications

Abstract

Cu doped ZnO film (Zn0.95Cu0.05O) was fabricated by simple and cost-effective screen printing method. The structural and optical properties of prepared film was studied through X-ray diffraction (XRD) and UV-Vis spectroscopy techniques respectively. XRD analysis revealed the polycrystalline nature of prepared film with hexagonal structure. The optical band gap determined from UV-Vis analysis was found to be 3.40 eV. The gas sensing performance of prepared film was studied at room temperature toward different concentrations of NO2 ranging in between 1ppm – 5ppm. The response and recovery time was noted as 13s and 92s respectively. All these outcomes shows that the Cu doped ZnO film shows enhanced gas sensing performance and can be utilized for industrial scale production of gas sensors.

“…[ 14,15 ] The spinel ferrite is promising over other magnetic materials due to its versatile nature, chemical stability, easy preparation, cost‐effectiveness, etc. [ 16 ] Among the spinel ferrite, copper and zinc have their own merits in physicochemical and properties. The copper ferrite is inverse structured, whereas zinc spinel ferrite possesses normal spinel behavior.…”
