Structure of Vanadium-Doped Zinc Oxide, Zn_1–XV_xO

Abstract

This work investigates the changes in the structural and magnetic properties due to the doping of vanadium in zinc oxide (with varying concentrations of vanadium, viz., 2%, 4%, and 6%) grown by solid state reaction method. The grown samples were analyzed through powder X-ray diffraction measurements, vibrating sample magnetometry (VSM), field emission scanning electron microscopy (FESEM), energy dispersive X-ray (EDAX) analysis, and UV-vis spectroscopy. The electronic structure of grown Zn 1-x V x O has been studied through maximum entropy method, which reveals an increasing trend in the size of the Zn atom and also becoming more covalent. M-H curves obtained from the VSM exhibit prominent room temperature ferromagnetism for x ¼ 0.04. FESEM and EDAX spectroscopy were employed for microstructure measurements.

Microemulsion synthesis, optical and photocatalytic properties of vanadium‐doped nano ZnO

“…It was reported that the method of synthesis and preparation has an important effect on the morphology, homogeneity, photocatalytic performance, and sinterability of ceramic powders . Some approaches for synthesizing V‐doped ZnO particles and ZnO‐V 2 O 5 composites have been proposed including solid‐state reaction, sol‐gel, co‐precipitation method, decomposition method, etc. To the best of our knowledge, a study focused on the preparation of V‐doped ZnO via microemulsion method and its photocatalytic properties has not been investigated.…”
