摘要
Hexagonal microtubes with hexagonal phase Y（OH）3 were successfully synthesized by a facile solvothermal method at 160°C for 12 h in the absence of surfactants or templates via a crystal transformation route. Scanning electron microscopy （SEM） results demonstrate that the prepared hexagonal microtubes are with a wall thickness of 50-100 nm, an outer diameter of 1 μm, and lengths going up tens of micrometers. Cubic phase Y2O3 microtubes were obtained after thermal treatment of the Y（OH）3 microtubes at 700 oC for 4 h. Eu^3＋-doped Y2O3 microtubes with strong red emission at 610 nm were also prepared and their photoluminescence （PL） properties were studied. The possible mechanism for the formation of the microtubes was briefly discussed.
