Cluster-like, flower-like and sphere-like EuPO 4 nano/microstructures and uniform core-shell SiO 2 @EuPO 4 nanostructures have been controllably synthesized by the hydrothermal route and co-precipitation method, respectively. The as-synthesized products are characterized by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS) and infrared spectroscopy (IR). The possible formation mechanism of the as-synthesized products is proposed. The photoluminescence properties demonstrate that the locations of the strongest peaks of nano/microstructured EuPO 4 and core-shell

“…Surface modification of NaYF 4 :Yb 3+ /Er 3+ upconversion nanoparticles not only improves photostability of the nanoparticles with desirable interfacial properties but also provides a potential platform for attaching biological macromolecules for various biomedical applications. − Furthermore, the biomedical labels need to have a specific property to target a specific tumor such as its surface must have suitable ligands that link to the cells. So, we covered the upconversion nanoparticle surface with a silica shell by the Stöber method.…”

Fluorescence imaging is an important technique used for early diagnosis and effective treatment of some incurable diseases including cancer. Herein, we report novel NaYF 4 :Yb 3+ / Er 3+ @silica-TPGS bio-nano complexes for labeling cancer cells. The NaYF 4 :Yb 3+ /Er 3+ nanoparticles have been successfully synthesized via a hydrothermal route, further coated with a silica shell, and functionalized with D-α-tocopheryl polyethylene glycol 1000 succinate (TPGS). The experimental results indicate that NaYF 4 :Yb 3+ /Er 3+ @silica-TPGS emits stronger upconversion luminescence than NaYF 4 :Yb 3+ /Er 3+ under an excitation of 980 nm. More significantly, the NaYF 4 :Yb 3+ /Er 3+ @silica-TPGS bio-nano complexes could strongly label MCF-7 breast cancer cells for in vitro experiments detected by a fluorescence microscope. On the other hand, the complex could not typically probe healthy cells, which are HEK-293A human embryonic kidney cells, under the same experimental conditions. Because of their strong upconversion luminescence, good dispersibility, and biocompatibility, NaYF 4 :Yb 3+ /Er 3+ @silica-TPGS bio-nano complexes can be a promising candidate/probe for biomedical labeling and diagnostics.

“…The transition observed at 593 nm ( 5 D 0 ? 7 F 1 ) is assigned to the magnetic dipole allowed transition of Eu 3+ [42]. Comparison of the core/shell (GdCP@EuCP) and EuCP downconversion luminescence emission spectrum showed that the emission intensity of the EuCP nanoparticles is stronger than the core/shell nanoparticles.…”
