摘要：

Nano crystalline Nickel Zinc ferrite (Ni0.25Zn0.75Fe2O4) thin films were synthesized by Sol Gel method for gas response. The phase and microstructure of the obtained Ni0.25Zn0.75Fe2O4 thin films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM). The nanostructured Ni0.25Zn0.75Fe2O4 thin film shows single spinel phase. Magnetic study was obtained with the help of VSM. The effects of working temperature on the gas response were studied. The results reveal that the Ni0.25Zn0.75Fe2O4 thin film gas sensor shows good selectivity to chlorine gas at room temperature. The sensor shows highest sensitivity (similar to 50%) at room temperature, indicating its application in detecting chlorine gas at room temperature in the future.
