Abstract
In this article, the characterization of internal structures and external surfaces of monodispersed particles by transmission electron microscopy (TEM) is overviewed with typical examples of monodispersed TiO2 and αFe2O3 particles. When monodispersed particles are less than 1 μm in diameter, their internal structure and external surface can be directly analyzed by TEM. On the other hand, particles larger than 1 μm should be sliced by ultramicrotomy to make thin sections for TEM. The complicated internal structure of monodispersed particles, such asαFe2O3 particles with a peanut shape, can be clarified through hi-ghresolution electron microscopy, electron diffraction, and energy-dispersive x-ray spectrometer analysis on their sections. Based on the analysis by TEM, the growth mechanism of monodispersed particles such as TiO2 can be understood through the simulation of their growth process.
