Abstract

A novel Fe3O4@WO3–x@YF3:Ce3+, Tb3+ imaging material was prepared by two-step method. Compared with the YF3:Ce3+, Tb3+, the luminescence intensity of Fe3O4@WO3–x@YF3:Ce3+,Tb3+ is obviously boosted. It showed that the protect effect and LSPR of WO3–x shielding layer play a role in enhancing the luminescence properties of the YF3: Ce3+, Tb3+. MTT assays showed that biomaterials have no poisonousness or harmful after-effects in cells. The magnetic saturation intensity is not obviously weakened by inserting WO3–x layer. The method can boost the luminescent property of the magnetic–luminescent material and stimulate its applications in cell imaging, targeting delivery, and thermotherapy.

Graphic abstract

In this study, Fe3O4@WO3–x@YF3:Ce3+,Tb3+ magnetic-luminescent bi-functional nanocomposites with best luminescent performance were synthesized by a simple direct precipitation method. Furthermore, the enhancement mechanism has been found as LSPR of WO3−x. The nanocomposites are potential application in tumor imaging and tumor precise surgery.
