Photoluminescence (PL) measurements on ZnO nanoparticles synthesized by chemical vapour synthesis (CVS) are presented. We show that the green defect related emission band can be almost completely suppressed by the right choice of processing parameters, like oxygen concentration and sintering temperature. Using temperature dependent time integrated and time resolved PL measurements we obtained information about the excitonic structure of the nanoparticles. (© 2006 WILEY-VCH Verlag GmbH & Co.
