摘要

采用超声波辅助Stöber法制备了多功能磁致发光纳米粒子。通过x射线衍射、拉曼散射光谱和透射电子显微镜(TEM)证实，该多功能NPs由磁性NPs (Fe3O4)和无定形二氧化硅(SiO2)基体中的光致发光量子点(ZnS:Mn)组成。该多功能NPs在室温下具有较高的饱和磁化强度，同时在可见光下具有较强的光致发光(PL)，在生物医学领域具有广阔的应用前景。

Synthesis and Characteristics of Multifunctional Magneto-luminescent Nanoparticles by an Ultrasonic Wave-assisted Stӧber Method

Multifunctional magneto-luminescent nanoparticles (NPs) were synthesised by an ultrasonic wave-assisted Stöber method. The multifunctional NPs are composed of magnetic NPs (Fe3O4) and photoluminescent quantum dots (QDs) (ZnS:Mn) in amorphous silica (SiO2) matrix, which was confirmed by X-ray diffraction, Raman scattering spectroscopy, and transmission electron microscopy (TEM). The multifunctional NPs have high saturation magnetisation at room temperature simultaneously with strong photoluminescence (PL) in visible light, which is promising for biomedical applications.
