Oxygen interstitials enhanced room temperature ferromagnetism in undoped zinc oxide
Source abstract
Abstract
Abstract Pure zinc oxide (ZnO) particles fabricated by a simple aqueous solution route were treated with hydrogen peroxide (H 2 O 2 ) solution. X-ray diffraction (XRD) and scanning electron microscopy (SEM) showed the homogeneous growth of particles throughout the substrate with the wurtzite phase. Magnetic properties were measured and a correlation between immersion time and ferromagnetism (FM) was observed. X-ray photoemission spectroscopy (XPS) and photoluminescence (PL) were then performed to investigate the influence of hydrogen peroxide (H 2 O 2 ) treatment on oxygen-related defects. It is revealed that oxygen interstitials (I O ) may be considered to be playing an important role in tailoring the magnetic properties of ZnO.
