abstract={The influence of growth parameters on the structural, morphological and optical properties of Mg<SUB>x</SUB>Zn<SUB>1-x</SUB>O grown on sapphire substrate by metal organic chemical vapor deposition is studied. Pure oxygen gas is used as oxidant, bis-methyl-cyclopentadienyl magnesium ((MeCp)<SUB>2</SUB>Mg) and diethyl zinc are used as Mg and Zn source, respectively. The growth temperature between and 320ˇăC and 620ˇăC, the VI/II (O/Mg, Zn) ratio ranging from 60 to 960 and the growth rate from 0.5 to 3.3 ?m/h, are systematically varied to determine their effects upon the above mentioned physical properties. Structural, morphological and optical properties of the thin films are characterized by means of X-Ray Diffraction (XRD), Scanning Electron?Microscope (SEM) and Photoluminescence (PL). Experimental results indicate that the growth conditions are essential for engineering the growth of Mg<SUB>x</SUB>Zn<SUB>1-x</SUB>O. The optimum substrate temperature is found to be 420ˇăC for the growth of Mg<SUB>x</SUB>Zn<SUB>1-x</SUB>O with a solid composition x below 30%, composition above which a phase segregation has been previously observed. With increasing temperature, strong parasitic reaction between (MeCp)<SUB>2</SUB>Mg and oxygen is found to occur before they rich the substrate.},
