文摘

Water-soluble lanthanide-doped YF₃ nanocrystals with cubic structure were successfully synthesized for the first time using a simple solvothermal method with ethanol as solvent at 160 °C for 12 h. SEM and TEM results demonstrated that the obtained nanocrystals have an irregular shape and an average size of below 30 nm. Tb³⁺, Tb³⁺/Ce³⁺ co-doped YF₃ nanocrystals were also prepared and their photoluminescence properties were investigated. The luminescent intensity of the Tb³⁺ for the Tb³⁺/Ce³⁺ co-doped YF₃ nanocrystals is about ten times higher than that of the Tb³⁺ doped YF₃ nanocrystals. The products were characterized by XRD, SEM and TEM. Owing to their water-soluble properties and high processability, extensive applications may be found.
