摘　　要：以Ca(NO3)2.4H2O,Eu2O3和(NH4)2HPO4为原料,采用反相微乳液-水热法制备出Eu3+掺杂羟基磷灰石纳米粒子。通过对产物纳米粒子的荧光光谱、TEM、XRD等测试分析,重点考察了Eu3+掺杂量对产物纳米结构和荧光性能的影响,并对荧光性能随其形貌变化的关系等进行了简要讨论。Luminescent europium doped hydroxyapatite nanoparticles were successfully fabricated via reverse microemulsion-directed hydrothermal methods from using calcium nitrate,europium oxide,diammonium hydrogen phosphate as raw materials.The structural,morphological,and optical properties of the product were well characterized by X-ray diffraction（XRD）,transmission electron microscopy（TEM）,and photoluminescence spectra（PL）.The influence of europium doped content on nanostructure and luminescent property of the product was investigated,and the relationship of the change of the luminescent intensity of the as-fabricated nanoparticles with their morphology was also simply discussed.
