中文摘要	znmgo hexagonal-nanotowers/films grown on m-plane sapphire substrates were successfully synthesized using a vertical low-pressure metal organic chemical vapour deposition system. the structural and optical properties of the as-obtained products were characterized using various techniques. they were grown along the non-polar [1 0 (1) over bar 0] direction and possessed wurtzite structure. the znmgo hexagonal-nanotowers were about 200 nm in diameter at the bottom and 120 nm in length. photoluminescence and raman spectra show that the products have good crystal quality with few oxygen vacancies. with mg incorporation, multiple-phonon scattering becomes weak and broad, and the intensities of all observed vibrational modes decrease. the ultraviolet near band edge emission shows a clear blueshift (as much as 100 mev) and broadening compared with that of pure zno products.
