Abstract
The 5% Fe-doped ZnO nanorods (Zn0.95Fe0.05O) were prepared successfully by the wet-chemical synthesis method. Structure and morphology characterization were demonstrated by X-ray diffraction (XRD) and transmission electron microscopy (TEM). Laser power dependent photoluminescence (PL) spectra were measured to study the electronic structures of the Fe-doped ZnO-based diluted magnetic semiconductors. The contraction of lattice constant and structured green-yellow-red emissions were analyzed. Such investigations confirmed that the induced defects or impurities originating from Fe ions.
