Abstract: In this study, the authors have investigated the optical properties of hydrothermally grown ZnO nanorods subjected to the combination of thermal annealing and nitrogen plasma treatments. In particular, ultraviolet-visible micro-Raman scattering has been used to study the influence of nitrogen incorporation in ZnO nanorods grown on GaN/sapphire templates. The band-edge photoluminescence spectra show significant changes due to nitrogen plasma treatment. In addition, visible Raman spectra show intensity enhancement of the disorder-activated vibrational modes from plasma-treated ZnO nanorods. Multiple longitudinal optical (LO) phonons are observed under ultraviolet resonant Raman excitation from these nanorods. The first-order resonant LO phonon line shape fitting is correlated to the nitrogen-induced lattice disorder. © 2008 American Institute of Physics.
