Abstract: Quasi- aligned Zn1-xMgxO nanorods have been synthesized on Si substrates by thermal evaporation. The Mg content ( x) in Zn1-xMgxO nanorods was 0.23, higher than that in the source materials by a factor of about 1.9. Zn1-xMgxO ( x = 0.23) nanorods showed a wurtzite ZnO structure with the c-axis constant of 0.5179 nm. The nanorods grew along the [ 0 0 0 1] crystal direction and had uniform and flat hexagonal planes with diameters of about 200 nm. Photoluminescence measurements revealed that the predominant ultraviolet ( UV) emission of Zn1-xMgxO ( x = 0.23) nanorods was centred at 3.78 eV, with a similar to 0.51 eV blueshift from the UV emission line ( 3.27 eV) of ZnO nanorods. This blueshift indicated the bandgap engineering in nanostructures of Zn1-xMgxO ternary alloys.
