In a previous paper, we reported that the reaction of cerium metal in 2‐methoxyethanol yielded a transparent colloidal solution of ultrafine (2 nm) ceria particles [M. Inoue, M. Kimura, T. Inui, Chem. Commun ., 957 (1999)]. In this paper, the solvothermal reaction of other rare‐earth metals in 2‐methoxyethanol has been examined. Reactions of Sm and Yb metals in 2‐methoxyethanol at 300°C yielded transparent colloidal solutions of Sm 2 O 3 and Yb 2 O 3 particles. However, the reaction of rare‐earth metals of Y, Eu, Gd, and Tb in 2‐methoxyethanol at 300°C resulted in recovery of the starting materials. Transparent colloidal solutions of the oxides of these elements were obtained by reaction in the presence of a small amount of acetic acid. The solvothermal reaction of rare‐earth metals in 2‐aminoethanol was also examined.
