- 摘要：
- We developed a novel cation exchange method to prepare the alloyed semiconductors. A series of self- assembled magnesium doped zinc oxide (MgxZn1-xO) particles were synthesised by varying the molar ratios of Mg precursor Mg-5(CO3)(4)(OH)(2)center dot 4H(2)O to Zn precursor ZnAc2 center dot 4H(2)O from 1: 1 to 3: 1 at different cation exchange time. Powder X-ray Diffraction (XRD) indicates that the samples are a mixture of hexagonal and cubic phases. The UV-visible (UV-vis) absorption spectra show that the band gap of MgxZn1-xO particles can be readily tuned by optimising the cation exchange time and the molar ratio of precursors. The morphology of MgxZn1-xO particles was observed by Scanning Electron Microscopy (SEM).
