Characterization of Voids in Rutile Nanoparticles by Transmission Electron Microscopy

Abstract

Rutile nanoparticles containing voids or cavities have been characterized using transmission electron microscopy. The general morphology of voids has been determined by obtaining images of particles in different orientations and by tilting nanoparticles around axes of interest. In general, the longest dimension is along the c axis of rutile. Many of the voids show a prismatic morphology with dipyramid terminations. The prism consists of primarily four (110) faces with rounded or faceted corners between the primary faces. The pyramidal terminations can appear ovoid or faceted. A major facet plane of the pyramids is (101). A possible model for the morphology of many voids in rutile nanoparticles is proposed.
