微反应器中LaPO4：Eu^3＋纳米棒的制备及表征

Preparation and characterization of LaPO_4:Eu^(3+) nanorods in a microreactor system

以Eu2O3、La(NO3)3.6H2O和NaH2PO4.2H2O为原料、乙二醇为溶剂,在微反应器中合成了铕掺杂磷酸镧(LaPO4:Eu3+)纳米棒。采用X射线衍射仪(XRD)、透射电子显微镜(TEM)和荧光光谱仪对LaPO4:Eu3+纳米棒的物相、微结构和荧光性能进行了表征。结果表明:LaPO4:Eu3+纳米棒具有六方晶系的晶体结构,形貌为长度100nm左右,直径10nm左右的针状纳米棒,并且具有较强的荧光性能。

Rare earth doped phosphate luminescent nanorods were prepared in a microreactor system in the ethylene glycol solution, using Eu2O3, La（NO3）3·6H2O and NaH2PO4·2H2O as raw materials. The crystal property, the shape and size of the nanorods of the LaPO4 ： Eu^3＋ nanorods were characterized by X-ray diffraction analysis （XRD）, transmission electron microscopy （TEM）. And the fluorescence property was detected by the fluorescence spectrum instrument. The results indicated that the nanorods prepared by a microreactor had hexagonal crystalline form, the nanorods with 100nm length and 10nm diametral and intensive fluorescence property.
