摘　　要：本实验以硝酸钇、三氯化钛和碳酸铵为原料,用共沉淀法制备出掺钛的氧化钇纳米粉体。前驱体在1100℃煅烧4h得到产品,经过XRD和FE-SEM测试,其平均直径约为60~90nm,掺Ti的Y2O3粉体在439nm处具有强荧光性。Y2O3 nanopowders doped Tia＋ were obtained by precipitation method. Yttrium nitrate, titanium trichloride and ammonium carbonate were used as starting materials. The precursor was calcined at 1100℃ for 4h.X-ray diffraction （XRD） and field scan electron microscope （FE-SEM） have been employed to characterize the products. It was found that the nanopowder sizes were about 60-90nm. The fluorescence emission wave of product was 439nm.
