以Ln(NO3)3·6H2 O(Ln=La ,Y ,Eu)和NaF为原料,采用AAO模板制备一维Lax Y1‐x F3纳米管、纳米线阵列。使用XRD、EDS、SEM和TEM分别对样品的结构、组成与形貌进行表征,并研究不同摩尔分数Eu3+掺杂的Lax Y1‐x F3纳米管的荧光性能。荧光光谱结果表明:Lax Y1‐x F3:Eu3+的发射光谱均由在593 nm (5 D0→7 F1)和711 nm (5 D0→7 F4)两组线状峰构成。样品的发光强度随Eu3+的摩尔分数的增大而存在一个极大值。实验结果表明,6% Eu3+掺杂的Lax Y1‐x F3纳米管的荧光性能最优。

The one‐dimensional LaxY1‐xF3 nanotube and nanowire arrays were synthesized with Ln(NO3 )3 (Ln=La ,Y ,Eu)and NaF solution via anodic aluminum oxide (AAO) template . The structure ,composition and morphology of LaxY1‐xF3 nanotube arrays were characterized using XRD ,EDS ,SEM and TEM ,respectively .The fluorescence properties of Lax Y1‐x F3 :Eu3+ nanotubes were also investigated by fluorescence spectrophotometer ,and the results indicated that there were two typical linear emission peaks near 593 nm (5D0 → 7 F1 ) and 711 nm (5D0 → 7F4 ) ,respectively .The emission intensities of the samples increased with the increase of the mole fraction of Eu3+ ion .When the doping Eu3+ ion was 6% in mole ratio , the luminescence intensity of LaxY1‐xF3 :Eu3+ nanotubes was the maximum .
