O-vacancies induced in co-doped ZnO:(Cu,Fe) synthesized via hydrothermal method by pulsed magnetic field

Parent ZnO nanoparticles dually doped (Cu, Fe) were synthesized by the hydrothermal method in the presence of variant pulse magnetic field (PMF) at (0, 4T). X-Ray diffraction (XRD) was used to find crystal structure, Scanning Electron Microscope (SEM) revealed that the transformation of elongated spheres into spheres with increasing magnetic pulse (4T), Raman scattering peaks appeared at 437.70 and 436.63 cm-1 belonged to ZFCO0T and ZFCO-4T indicated defects and inclusion of dopant elements in parent sample, XPS analysis showed that the decline in compressive strain enhances the contents of vacancies of oxygen (VO) for ZFCO-4T sample, and Bound Magnetic Polarons (BMPs) explained the RTFM order i.e.the sample ZFCO-4T has a higher number of polarons and they overlap excellently.
