Band gap tuning and defects suppression upon Mg doping in electrospun ZnO nanowires
Abstract We report the synthesis of inter-twinned ZnO nanowires doped with $ Mg^{2+} $ by electrospinning polyvinyl alcohol along with metal oxide precursors followed by heat treatment 650 °C for 3 h in air. Mg doping influences the morphology of the nanofibers as well as the structure and optical p...

| 520 | |a Abstract We report the synthesis of inter-twinned ZnO nanowires doped with $ Mg^{2+} $ by electrospinning polyvinyl alcohol along with metal oxide precursors followed by heat treatment 650 °C for 3 h in air. Mg doping influences the morphology of the nanofibers as well as the structure and optical properties of the heat treated samples. Up to 5 wt% Mg doping, single phase wurtzite structure of ZnO is retained. Optical bandgap energy of ZnO nanowires could be tuned over the range of 3.25–3.56 eV by increasing Mg doping up to 8 wt%. Interestingly, defects present in undoped ZnO decreased drastically upon doping with Mg. | ||

Band gap tuning and defects suppression upon Mg doping in electrospun ZnO nanowires |
| abstract |
Abstract We report the synthesis of inter-twinned ZnO nanowires doped with $ Mg^{2+} $ by electrospinning polyvinyl alcohol along with metal oxide precursors followed by heat treatment 650 °C for 3 h in air. Mg doping influences the morphology of the nanofibers as well as the structure and optical properties of the heat treated samples. Up to 5 wt% Mg doping, single phase wurtzite structure of ZnO is retained. Optical bandgap energy of ZnO nanowires could be tuned over the range of 3.25–3.56 eV by increasing Mg doping up to 8 wt%. Interestingly, defects present in undoped ZnO decreased drastically upon doping with Mg. © Springer Science+Business Media New York 2017 |
