| Abstract: | The Mg- and In-doped zinc oxide (Mg

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

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. |
