摘要

在水溶液中采用化学共沉淀法制备了壳聚糖/LaF

∶ Eu

纳米复合粒子。通过透射电子显微镜(TEM)

X射线衍射(XRD)

傅立叶变换近红外(FT-IR)光谱对样品进行了表征。结果表明:所得纳米复合粒子大小在 20 nm左右

粒径均匀

表面包覆的壳聚糖使其易溶于水

并具备了与生物蛋白偶联的多个基团。测量了该纳米复合粒子的激发光谱与发射光谱

详细说明了各发光峰对应能级的跃迁及其发光机理

分析了不同掺杂浓度对其相对发光强度的影响。结果表明:当 Eu

离子掺杂摩尔分数为 10%时

样品的相对发光强度达到最大值。最后介绍了壳聚糖/LaF

∶ Eu

纳米复合粒子与荧光蛋白 FITC偶联的方法

以表明其在生物学中潜在的应用价值。
