采用负压抽滤法,在多孔纳米氧化铝模板(AAO)中制备CexCo1-xOy:Eu3+纳米线阵列.以SEM、TEM、XRD和EDS,对CexCo1-xOy:Eu3+纳米线阵列形貌、结构和元素组成进行表征,用PerkinElmer LS-55型荧光光谱仪对CexCo1-xOy:Eu3+纳米线荧光强度进行检测.结果表明:CexCo1-xOy:Eu3+纳米线为非晶态结构,纳米线尺寸均一、形貌可控.向CexOy:Eu3+纳米线掺杂Co3+时,随着Co3+摩尔百分比增大,CexCo1-xOy:Eu3+纳米线荧光发射强度逐渐减弱,当Co3+掺杂浓度达到15%时,导致CexCo1-xOy:Eu3+纳米线荧光猝灭,此可为医疗传感材料及器件设计提供技术支撑.
CexCo1-xOy: Eu3 + nanowire arrays were prepared by vacuum suction filtration in the presence of nano-alumina template (AAO). The morphology and structure of CexCo1-xOy: Eu3 + nanowire arrays were investigated by SEM, TEM, XRD and EDS Elemental composition, the fluorescence intensity of CexCo1-xOy: Eu3 + nanowires was measured by PerkinElmer LS-55 fluorescence spectrometer.The results showed that the nanocrystalline CexCo1-xOy: Eu3 nanowires were amorphous and the nanowires were uniform in size and morphology The emission intensity of CexCo1-xOy: Eu3 + nanowire decreases gradually with the increase of the mole fraction of Co3 + when Ce3Oy: Eu3 + nanowires are doped with Co3 +. When the concentration of Co3 + reaches 15%, the emission of CexCo1-xOy: Eu3 + Nanowire fluorescence quenching, which provides technical support for the design of medical sensing materials and devices.
