摘要: Abstract Oleic acid (OA)-modified CaF 2 :Tb 3+ nanoparticles with various Tb concentrations and :Ce , were synthesized. The as-prepared shown to be well dissolved in some common organic solvents, such as chloroform toluene. characterized by Fourier transform infrared spectroscopy (FT-IR), X-Ray diffraction (XRD) transmission electron microscopy (TEM). investigation of fluorescence properties showed that the ions could sensitized efficiently surface coating OA 10 mol% possess highest emission intensity. comparison for (10 mol%) revealed intensity former is about 4.5 times strong latter.
