In this work, a double-layered fluorescent nanomaterial YPO₄: Sm³⁺@YPO₄@PEG (PEG=polyethylene glycol) was constructed by using hydrothermal and microwave methods, to improve the hydrophobicity and fluorescence properties of rare-earth phosphates. Firstly, the core-shell nano-luminescent material YPO₄: Sm³⁺@YPO₄ was prepared by adjusting the molar ratio of YPO₄: Sm³⁺ and YPO₄ to prepare the core-shell structure with various ratios of core diameter and shell thickness, and the optimal molar ratio was obtained. YPO₄: Sm³⁺@YPO₄@PEG was prepared with PEG as the coating. The structure, morphology, and fluorescence properties of the product were characterized by X-ray diffraction, scanning electron microscope, transmission electron microscope, Fourier transform infrared spectra, and fluorescence spectra. Finally, the results show that the produced nano-phosphor is a singlephase material with a tetragonal unit cell (YPO₄). The product is not affected by the coating; the particles of the material had spherical morphology with a diameter of 60-100 nm, and the thickness of the coating layer was about 10-20 nm. The fluorescence intensity of YPO₄: Sm³⁺@YPO₄@PEG with the double-layered core-shell structure was more than six times stronger than that of nano-phosphor YPO₄: Sm³⁺ without the core-shell structure. In conclusion, the double-layered fluorescent nanomaterial has hydrophilicity and biocompatibility, menanwhile enhanced fluorescence intensity of YPO₄: Sm³⁺.
