The Raman spectrum corrected for the PL background of the (in units of relative wavenumbers). The left inset shows the original spectrum, where the PL peak position is marked in units of eV. The spectrum was acquired at 77K. The 7LO has a resonance coinciding with the PL at . The right inset shows the PL of a ZnO ceramic which has a PL intensity that is about two orders of magnitudes higher than that of the .
