摘要:以Y2O3Eu2O3 为原料,NH3?H2O NH4HCO3 为沉淀剂,采用共沉淀法,在700 1200下煅烧2h 制备出Y2O3Eu3+纳米粉体,通过X 射线衍射分析(XRD)、扫描电镜(SEM 和荧光分光光度计等表征样品的性能,研究不同掺杂浓度,不同烧结温度及不同沉淀剂对粉体各项性能的影响。结果表明,以两种沉淀剂制备的纳米粉体均为纯相,与Y2O3标准PDF 卡片41-1105 相吻合。以NH3?H2O 为沉淀剂制备出来的前驱体在1100下煅烧2h 获得的粉体分布均匀,近似球形,粒径分布在50~80nm,以NH4HCO3为沉淀剂制备出来的前驱体在1100下煅烧2h 获得的粉体分布均匀,纯度高,具有良好的分散性,粒径分布在60~80nm。制备出来的粉体在波长为254nm 的紫外光激发下发出611nm 的红光。

AbstractY2O3Eu3+ nano-powders were prepared by using co-precipitation method with Y2O3 and Eu2O3 as rawmaterialsNH3 ?H2O and NH4HCO3 as the precipitant calcining at 700~1200 for 2h.The synthesized Y2O3 Eu3 + nano-powders with different Eu3+ doping ratiocalcining temperatures andprecipitants were characterized by X-ray diffractometry XRD), Scanning electron microscopy SEM and fluorescence spectrophotometer.The results illustrated that the diffraction peaks of samples are well consistent with JCPDS No.41-1105. The nanopowders with NH3?H2O as the precipitant calcined at 1100 for 2h had a uniform distribution approximating sphere. The particle size was in the range of 50~80nm.The nano-powders with NH4HCO3 as the precipitant calcined at 1100 for 2h had an uniform distributionhigh purity and good dispersibility. The particle size was in the range of 60~80nm.The nano-powders emitted the red light at the 611nm under the UV-light with 254nm excited.
