MgXZn1?XO nanofibers with different doping concentration were prepared by atom layer deposition (ALD) using polyvinyl pyrrolidone (PVP) nanofibers as template. The influence of Mg doping concentration on the structure and optical properties of composite nanofibers were investigated. The samples were characterized by field emission scanning electron microscopy (FESEM)，ultraviolet visible（UV-vis）absorption spectroscopy and photoluminescence (PL) spectra. The morphologies of all the samples were not changed while the diameter of MgXZn1?XO-PVP composite nanofibers became larger after doping. With increasing Mg doping concentration, the absorption edge shifted to larger energy side, revealing the band gap tunability of MgXZn1-XO nanofibers. Meanwhile, a significant blue shift of the UV emission peak from 377nm to 362nm was observed in PL spectra. Compared with ZnO-PVP composite nanofibers, the UV emission intensity of MgXZn1?XO-PVP composite nanofibers were much stronger.
