Abstract

A family of monodisperse YF ₃, YF ₃:Ce ³⁺ and YF ₃:Ce ³⁺/Ln ³⁺ (Ln=Tb, Eu) mesocrystals with a morphology of a hollow spindle can be synthesized by a solvothermal process using yttrium nitrate and NH ₄F as precursors. The effects of reaction time, fluorine source, solvents, and reaction temperature on the synthesis of these mesocrystals have been studied in detail. The results demonstrate that the formation of a hollow spindle-like YF ₃ can be ascribed to a nonclassical crystallization process by means of a particle-based reaction route in ethanol. It has been shown that the fluorine sources selected have a remarkable effect on the morphologies and crystalline phases of the final products. Moreover, the luminescent properties of Ln ³⁺-doped and Ce ³⁺/Ln ³⁺-co-doped spindle-like YF ₃ mesocrystals were also investigated. It turns out that Ce ³⁺ is an efficient sensitizer for Ln ³⁺ in the spindle-like YF ₃ mesocrystals. Remarkable fluorescence enhancement was observed in Ce ³⁺/Ln ³⁺-co-doped YF ₃ mesocrystals. The mechanism of the energy transfer and electronic transition between Ce ³⁺ and Ln ³⁺ in the host material of YF ₃ mesocrystals was also explored. The cytotoxicity study revealed that these YF ₃-based nanocrystals are biocompatible for applications, such as cellular imaging.
