■要約
Monodispersed particles are defined as the particle system of excellent uniformity in size, shape, structure, and composition. Because of this extraordinary homogeneity, they have originally high function. Among them, metal oxide nanoparticles have been utilized in many fields in engineering so that they are well friendly to us in our life. Figure 1 exemplifies monodispersed Na0.5K0.5NbO3 fine particles with well-controlled nanostructure for lead-free piezoelectric device. Needless to say, they have highly functional characteristics. This paper will be focused on the preparation of metal oxide nanoparticles with excellent monodispersity in material properties. In addition, we will show Anatase-type uniform TiO2 nanoparticles with different shape and size for photocatalysts, as well as indium tin oxide (ITO) nanoparticles precisely controlled for transparent conductive oxide film in electrical materials.
