Abstract
Ni-doped ZnO (NZO) thin films were prepared onto a glass substrate with varying concentrations of 2, 4, 6, 8, 10% of Ni using sol-gel spin coating method and their structural, optical and magnetic characteristics were discussed with supporting of XRD, UV, Photoluminescence, XPS and vibrating sample magnetometer (VSM) characterization techniques. The XRD analysis shows that the polycrystalline hexagonal wurtzite structure with (002) orientation of NZO thin films. The XPS results confirmed the presence of Ni ion in all the samples. The optical bandgap of the prepared samples was decreased with increasing concentrations of nickel from 3.33 to 3.22 eV. Photoluminescence spectra showed a red shift of near band edge (NBE) and deep level (DLE) emissions for prepared undoped and NZO thin films. The VSM of prepared NZO thin films exhibit ferromagnetic behavior at room temperature for potential applications in various fields. Our experimental observations support for transparent conducting electrode and spintronics device applications.
期刊介绍:
Topics in Catalysis publishes topical collections in all fields of catalysis which are composed only of invited articles from leading authors. The journal documents today’s emerging and critical trends in all branches of catalysis. Each themed issue is organized by renowned Guest Editors in collaboration with the Editors-in-Chief. Proposals for new topics are welcome and should be submitted directly to the Editors-in-Chief.
The publication of individual uninvited original research articles can be sent to our sister journal Catalysis Letters. This journal aims for rapid publication of high-impact original research articles in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
