| Outline of Final Research Achievements |
Solutions made from glymes as main solvents and an ionic liquid ingredient as a co-solvent were investigated in order to clarify if they offer a possibility of electrochemically stable, low viscous, and low volatile baths for rare earth electrodeposition. When RCl3 (R = rare earth ions) were chosen as rare earth salts, baths with the concentration of approximately 50 mmol dm-3 were able to be prepared, but their conductivities were poor. In the case of rare earth amide salts R(Tf2N)3 and TMPA-Tf2N (a trimethyl-n-propylammonium amide salt) co-solvent, conductivity was improved while crystalline, metallic rare earth electrodeposits had not been obtained. Because of that, electrodeposition of rare earths was tried using the combination of aqueous solutions and (meso)porous silicon electrodes. As a result, a film compound consisting of Co and Tb was successfully obtained.
