摘　　要：依据化学共沉积原理,在阳极氧化铝(AAO)纳米阵列孔模板中,用负压抽滤法可控合成了CeNdxOyEu^3+纳米管阵列结构材料.分别用SEM,TEM,XRD,SAED对其形貌、结构进行表征,并以EDS谱和荧光光谱仪(FL)测定该纳米管结构的元素组成和荧光性能.结果表明:CeNdxOyEu^3+纳米管阵列材料为非晶结构,其纳米管阵列形貌与AAO模板纳米孔阵列结构一致.在室温下,以450 nm波长光激发CeNdxOyEu^3+纳米管阵列,分别在516 nm和777 nm出现荧光发射峰,其荧光强度与Eu^3+掺杂量有关,当Eu^3+掺杂质量比为6%时,其荧光强度最强.Based on the principle of chemical coprecipitation,CeNdxOy:Eu^3+nanotube arrays were synthesized in an anodic aluminum oxide(AAO)nano-array porous templates by assisted negative pressure filtration.The morphology and structure were characterized by SEM,TEM,XRD and SAED,respectively,and the elemental composition and fluorescence performances of the CeNdxOy:Eu^3+nanotube arrays were studied by EDS spectroscopy and fluorescence(FL)spectrometer as well.The results showed that the CeNdxOy:Eu^3+nanotube arrays were an amorphous structure,and its morphology was uniformity and consistence with the AAO template nanopores arrays.At room temperature,the CeNdxOy:Eu^3+nanotube arrays were excited with 450 nm light,and the fluorescence emission peaks appeared at 516 nm and 777 nm,respectively.The fluorescence intensity was related to the Eu^3+doping amount.When the Eu^3+doping mass ratio was 6%,its fluorescence intensity was the strongest.
