摘要: Abstract LaF 3 :Eu 3+ and GdF nanoparticles were prepared by a co-precipitation method in the presence of chelating agent, citric acid. The structural properties products characterized X-ray diffraction (XRD) transmission electron microscopy (TEM). average crystallite size was estimated from full-width at half-maximum (FWHM) peaks Scherrer equation. sizes 12 nm for 17 . luminescent investigated excitation emission spectra. Energy transfer Gd to Eu observed.
