Abstract

In this study, the authors have investigated the structural and optical properties of ZnO nanorods grown on c-sapphire substrates by metal organic chemical vapor deposition. The presence of strong band-edge emission and higher-order LO phonon scattering in resonant Raman process confirms the good optical quality ZnO nanorods. The observation of strong E₂^high optical phonon mode in the visible Raman spectra at 438 cm^-1 justifies the wurtzite nature of ZnO. The ultraviolet resonant Raman scattering measurements on such nanorods show higher-order LO phonon modes and a frequency upshift at higher growth temperature.
