Uniform Lu-2(C4H4O6)(3)center dot 6H(2)O cauliflower-like microspheres have been synthesized via a direct precipitation method at room temperature, without any templates and catalysts. The solvent-dependent morphological evolution and the formation mechanism of the Lu-2(C4H4O6)(3)center dot 6H(2)O cauliflower-like microspheres were investigated in detail. Furthermore, Eu3+/Tb3+-doped Lu2O3 inherited their parents' morphology were obtained through a direct annealing process. The Lu-2(C4H4O6)(3)center dot 6H(2)O:Eu3+, Lu2O3:Eu3+ exhibit strong red emission corresponding to the D-5(0)-F-7(j) transition of the Eu3+ ions. The Lu-2(C4H4O6)(3)center dot 6H(2)O:Tb3+, Lu2O3:Tb3+ exhibit strong green emission corresponding to the D-5(4)-F-7(j) transition of the Tb3+ ions under UV light excitation. The samples may have potential applications in the fields, such as light-emitting phosphors, advanced flat panel displays, or biological labeling.
