Abstract
Layers of ZnO nanoparticles with thicknesses of about 40 nm were prepared on Si substrates It was shown that UV laser irradiation is suitable for consolidation and significant densification of the ZnO particle layers under ambient conditions Both experiments and simulations show that an underlying SiO2 particle layer has a beneficial effect in inhibiting heat transfer towards the substrate and thus enables the application of temperaturesensitive carrier substrates like polymer foils despite the extremely high melting temperature of ZnOThe support of the Deutsche Forschungsgemeinschaft DFG Graduiertenkolleg 1161/2 is gratefully acknowledged Additionally we are thankful for the support by Evonik Industries AG and also for the production of particle suspensions by Daniel Kilian Furthermore we want to thank Anke Haas for operating the electron microscope Moreover the authors gratefully acknowledge funding of the Erlangen Graduate School in Advanced Optical Technologies SAOT by the German Research Foundation DFG in the framework of the German excellence initiative
