Mg doping reduced full width at half maximum of the near-band-edge emission in Mg doped ZnO films 下载免费PDF全文
Sol--gol method was employed to synthesize Mg doped ZnO
films on Si substrates. The annealing temperature-dependent
structure and optical property of the produced samples were studied.
An interesting result observed is that increasing Mg concentration
in the studied samples induces the full width at half maximum (FWHM)
of their near-band-edge (NBE) emission decrease and the defect
related emission of the corresponding sample suppresses drastically.
The possible mechanism of the observed result is discussed. 相似文献
