Abstract

The quasi-LO phonon mode is related to the specific defects that strongly affect the photonic properties of materials such as zinc oxide (ZnO). The line shapes of the quasi-LO phonon of ZnO annealed in different environments have been investigated. The experimental results show that this mode has the greatest Raman shift to lower wavenumber for the ZnO annealed in ambient atmosphere, suggesting that it has the largest concentration of defects that may be related to its green emission. © 2008 American Institute of Physics.
