Cross-like Pr-2(C2O4)(3)center dot 10H(2)O micro-particles were synthesized through a simple precipitation method at room temperature. The products were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), field-emission scanning electron microscopy (FESEM), thermogravimetry differential thermal analysis (TG-DTA) and photoluminescence (PL). The possible formation mechanism of the cross-like Pr-2(C2O4)(3)center dot 10H(2)O micro-particles was discussed, and Pr6O11 with similar morphology was obtained by calcining the oxalate precursor.
