A Simple Method to Synthesize Dy(OH)₃ and Dy₂O₃ Nanotubes

Abstract

Here we report the first synthesis of Dy(OH)(3) nanotubes by facile hydrothermal treatment of bulky Dy(2)O(3) crystals. Dy(OH)(3) nanotubes were calcined to produce Dy(2)O(3) nanotubes. Ho(OH)(3) and Ho(2)O(3) nanotubes were also obtained by the same method. The growth of nanotubes occurred through a dissolution-recrystallization process.
