Abstract
A facile method was developed to synthesize Eu doped LuO(OH) nanorods through hydrothermal processing and Lu2O3 nanorods by subsequent calcining. The microstructural morphologies of the Lu-based nanostructures could be controlled by simply varying the concentration of NaOH in hydrothermal processing as mineralizer. TEM observation revealed that the obtained LuO(OH) nanorods after hydrothermal processing had a uniform diameter of 10–25 nm and a length around 100 nm. After heat treatment at 600–700°C for 2 h, the high length/diameter ratio was sustained in the obtained Lu2O3 nanorods with different sizes depending on the calcining temperatures.
