摘 要：In this work,a facile route using a simple solvothermal reaction and sequential heat treatment process to prepare porous Y2O3 microcubes is presented.The as-synthesized products were characterized by X-ray powder diffraction（XRD） ,scanning electronic microscope（SEM） ,en-ergy dispersive spectrometer（EDS） ,thermogravimetric analysis（TG） ,and differential thermal analysis（DTA） .The thermal decomposition process of the Y2O3 precursor was investigated.SEM results demonstrated that the as-prepared porous Y2O3 microcubes were with an aver-age width of about 20 μm and thickness of about 8 μm.It was found that the morphology of the Y2O3 precursor could be readily tuned by varying the molar ratio of S 2 O 82-to Y3+.Y2O3:Eu3+（6.6%） microcubes were also prepared and their photoluminescence properties were investigated.
