Hydrothermal synthesis of spindle-like architectures of terbium hydroxide

Abstract

The spindle-like architectures consisting of Tb(OH)₃ nanowires were successfully prepared from Tb₂O₃ powder by hydrothermal treatments in acetic acid solutions without adding other surfactants. The products were characterized by XRD, FE-SEM and FT-IR. The influence of the concentration of acetic acid, reaction temperature and reaction time on the crystalline phases and morphologies of the products was investigated. The concentration of acetic acid plays a key role in determining the morphology of the Tb(OH)₃ products. The effect of acetic acid on the morphologies of the products was systematically discussed.
