In this work, undoped YVO4nanocrystals (10–15 nm in size) were first synthesized by a solvothermal method, and they were ion exchanged for Eu3+ions to form YVO4:Eu3+nanocrystals, which were then used to prepare YVO4:Eu3+–thenoyltrifluoroacetone hybrid nanostructures. As expected, the ion exchanged YVO4:Eu3+nanocrystals exhibited the characteristic V–O charge transfer excitation band. Much stronger luminescence has been observed in the YVO4:Eu3+–thenoyltrifluoroacetone hybrid nanostructures due to energy transfer from thenoyltrifluoroacetone ligands to Eu3+ions. The dependence of luminescence of the YVO4:Eu3+–thenoyltrifluoroacetone hybrid nanostructures on the Eu3+concentration and amount of thenoyltrifluoroacetone ligands was investigated in detail, and optimal preparation conditions were determined. Their UV–Vis absorption spectra and BET specific surface area were measured. X-ray diffraction technique, transmission electron microscopy, and Fourier transform infrared spectroscopy were used to study their microstructural characteristics.
