摘要
以水为溶剂,氨基酸为模板剂,通过微波辅助水热方法合成了YVO4∶Eu纳米粒子.该纳米粒子具有结晶化程度高、稳定性好及尺寸小(<50 nm)等特点,且在水中具有良好的分散性.探究了氨基酸加入量对纳米粒子结构及形貌的影响,并将该合成方法用于其它稀土钒酸盐.在紫外光激发下,YVO4∶Eu纳米粒子表现出优异的荧光性能(发射明亮的红光),可将其与柔性聚合物复合用于简易的三维(3D)图像显示.此外,YVO4∶Eu纳米粒子还可作为荧光探针用于标记小鼠结肠癌细胞(CT26细胞).
Amino acid capped YVO4∶Eu nanoparticles were synthesized via a facile and green microwave-{assisted}hydrothermal method with water as solvent and amino acid as template agent.The as-prepared nano-{particles}have good crystallinity,high water-dispersibility and small size(<50 nm).Meanwhile,the effects of adding amounts of amino acids on the structure and morphology of synthetic nanoparticles were also studied in detail.This synthetic method is equally suitable for the synthesis of other rare earth vanadates.The YVO4∶Eu nanoparticles exhibit excellent luminescent property under UV light excitation.It was compounded with a{flexible}polymer for simple 3D image display.YVO4∶Eu nanoparticles can also be used as fluorescent probes to label mouse colon cancer cells(CT26 cells).
