Paper Abstract

ZnO nanoparticles are a challenging material to disperse and stabilize due to their high density, tendency to aggregate and chemical properties. Manufactured ZnO nanoparticles often posses a high degree of size and shape dispersity, adding additional complexity to both sample preparation and subsequent characterization. In this paper, procedures for achieving stable and representative dispersions of ZnO nanoparticles from commercially available sources are discussed, and the average particle size determined from dynamic light scattering measurements is qualitatively evaluated against transmission electron microscopy images. The results highlight a number of important issues that need to be taken into consideration when performing a metrological assessment of particle sizes and size distributions in such systems.
