摘要
To realize the magnetic field sensing, pristine and Mn doped ZnO nanorods coated fiber optic sensor is proposed and experimentally demonstrated. In order to create both pristine and Mn-doped ZnO nanorods (5, 10, 15 and 20 at. %), the hydrothermal approach was used and subjected towards various characterization techniques such as XRD, SEM, EDS and XPS. The XRD data show that ZnO crystallized in wurtzite structure, while samples of ZnO doped with Mn (5, 10, 15 and 20 at. %) contained ZnMnO3 impurity phase. The Mn doped ZnO nanorods served as the sensing component of the sensor structure made up of cladding modification technology. The magneto-refractive effect serves as the sensing principle. The effect of applied magnetic field on Mn doped ZnO nanorods coated cladding modified fiber optic sensor was investigated in detail. According to experimental findings, the sensor has an operational magnetic field range of 17.2 mT–190.6 mT and exhibits a maximum sensitivity of 27.2 for Mn doped ZnO nanorods (15 at. %) along with short response/recovery time of 7 s/12 s. The proposed sensor would be appealing due to its low manufacturing cost, reliable sensing structure, and high sensitivity, enabling potential applications in magnetic field measurements.
