The lanthanide-doped GdF 3 nanoparticles have been produced by a simply hydrothermal synthesis procedure. The excitation and emission spectra of the Eu 3+ -doped GdF 3 nanoparticles showed that the excitation energy of Gd 3+ is efficiently transferred to Eu 3 + in the Eu 3+-doped GdF 3 nanoparticles. Due to very low phonon energies of GdF 3 matrix, the 5D 1 emission of Eu 3+ ions in the Eu 3+ -doped GdF 3 nanoparticles can be observed at room temperature when the doping concentration of Eu 3+ ions is lower than 15 mol%. The luminescence intensity of the Eu 3+-doped GdF 3 nanoparticles increased with increasing concentration of Eu 3+ ions and reached a maximum at approximately 15 mol%. The Er 3+-doped GdF 3 nanoparticles exhibit the typical emission spectra of Er 3+ in the near-infrared region. The upconversion emission of the Er 3+/Yb 3+ codoped GdF 3 nanoparticles can also be observed. However, the upconversion emission intensity of the Er 3+/Yb 3+-codoped GdF 3 nanoparticles was much weaker than that of the Er 3+/Yb 3+-codoped GdF 3 bulk crystal. © 2006 IEEE.
