| Outline of Final Research Achievements |
A variety of unprecedented alloy nanoparticles have been successfully synthesized by galvanic replacement reactions of nanoparticles in which p-block elements have been introduced into d-block metal nanoparticles, and in manifesting novel plasmonic properties. By utilizing the interelement miscibility, unprecedented Z3-type nanoparticles have been synthesized for the first time. On the other hand, considering the characteristic that the anion sublattice is maintained in the cation exchange reaction of ionic nanoparticles, thermodynamically metastable spinel-type Ni3Se4 nanoparticles and Cu2-xSe/Ni3Se4 heterostructure nanoparticles have been successfully obtained by cation exchange between Cu2-xSe nanoparticles and Ni(II). Furthermore, in the cation exchange reaction of hexagonal Cu1.8S nanoparticles, we have clarified the factors that determine the crystal structure of the nanoparticles after cation exchange.
