Zinc magnesium oxide nanofibers on glass substrate by solution growth technique

摘要

Zinc magnesium oxide [Zn_(1-x)Mg_xO (0≤x≤0.2)] nanofibers were grown by solution growth technique on glass substrate having zinc oxide (ZnO) seeds deposited onto them. The films were dense and characterized by strong reflections from (002) planes followed by reflections from (220) planes. Band gap varied between 3.14 and 3.75 eV with magnesium content varying between 0.05 and 0.20. Photoluminescence (PL) spectra recorded at 10 K for ZnO nanorods were dominated by a strong luminescence peak in the UV region at ～3.13 eV. With the addition of Mg in the ZnO lattice, a low-intensity PL peak started appearing in the blue region (～2.62-2.65 eV). The films were also characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR) and Raman measurements.
