Abstract: 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 Mg5(CO3)4(OH)2•4H2O to Zn precursor ZnAc2•4H2O 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).
