A facile method was developed to synthesize Eu doped LuO(OH) nanorods through hydrothermal processing and Lu 2 O 3 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 Lu 2 O 3 nanorods with different sizes depending on the calcining temperatures. nanorods, hydrothermal processing, LuO(OH), Lu 2 O 3 Citation:Qiu H J, Shi Y, Xie J J, et al.
