| 摘要 | X-rayabsorption near-edge structure (XANES) and x-ray emission spectroscopy (XES) measurements were used to investigate the effect of Mgdoping in ZnOnanorods. The intensities of the features in the O K-edge XANES spectra of Zn1−xMgxOnanorods are lower than those of pure ZnOnanorods, suggesting that Mgdoping increases the negative effective charge of O ions. XES and XANES spectra of O 2p states indicate that Mgdoping raises (lowers) the conduction-band-minimum (valence-band-maximum) and increases the band gap. The band gap is found to increase linearly with the Mg content, as revealed by photoluminescence and combined XANES and XES measurements. |
