Effects of In and Mg doping on properties of ZnO nanoparticles by flame spray synthesis

The Mg- and In-doped zinc oxide (Mg x Zn 1− x O, In y Zn 1− y O) nanoparticles were successfully prepared by flame spray synthesis method. According to the results obtained from X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and UV–Vis absorption...

Zusammenfassung:The Mg- and In-doped zinc oxide (Mg x Zn 1− x O, In y Zn 1− y O) nanoparticles were successfully prepared by flame spray synthesis method. According to the results obtained from X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and UV–Vis absorption spectra, it was concluded that the Mg or In doping induced the lattice constants to change to some extent; the band gap of Mg x Zn 1− x O also increased with respect to the decreasing band gap of In y Zn 1− y O. Moreover, the strong UV emission and weak visible emission were investigated by photoluminescence spectra, while the mechanisms of Mg or In doping on PL spectra have been discussed in detail.
