| Abstract: Shuttle-like hexagonal NaNdF4 nanocrystals with a diameter of 100 nm at the middle and a length of 250 nm were synthesized at room temperature. Shuttle-like NaEuF4, NaSmF4, NaGdF4, and NaTbF4 nanocrystals were also synthesized using the same method. The products were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), high resolution TEM (HRTEM), field emission scanning electron microscopy (FESEM), and photoluminescence (PL). PL spectra of the as-synthesized NaEuF4 showed an excitation source wavelength of 394 nm. NaEuF4 had four major emission bands at 591, 615, 650 and 681 nm. |
