| Research Abstract |
The purpose of this study is the establishment of three dimensional structure analysis using ultramicrotomy and image processing. First of all, we found the optimum slice conditions for ultramicrotomy of ion oxide small particles. Actually we succeeded in obtaining successive thin section with several ten nm in thickness. Then we carried out high-resolution electron microscopy with a high-voltage high resolution electron microscope in Tohoku University. In order to accurately record the high-resolution images, we used a new recording system, i.e., the imaging plates. We also carried out the imaging processing using Tohoku University computer network system TAINS and SUPER-TAINS.Through these studies, we clarified internal structure of monodisperse ion oxides with various shapes, such as platelet-type, peanut-type and pseudocubic type. We also applied this method to CdS monodisperse particles and succeeded in clarifying their internal and external structure.
