A study of the effects of chemomechanical polishing on the room temperature photoluminescence of both polar faces of ZnO single crystals is presented. A distinct peak which we associate with second order exciton–phonon (FX–2LO) emission and which dominates the LO emission for both (0001) and () etched surfaces is observed. Chemomechanical polishing results in reduction of the distinct FX–2LO peak, and an increase in the relative importance of first order exciton–phonon (FX–1LO) emission. We attribute this to disorder introduced by the polishing process.
