Abstract

A kind of monodisperse LaF3:Nd nanocrystal with a small size and long lifetime in solvent was synthesized via a hydrothermal process. The crystalline phase, morphology, and luminescence properties were characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM), emission spectroscopy as well as dynamic decays. The results indicated that LaF3:Nd nanocrystals with a size below 30 nm have great dispersity in various solvents. An excellent lifetime of 359 μs was detected in a transparent DMSO–tetrabromoethane dispersion. It suggested that these nanocrystals could have great applications in biological and optical amplification fields.
