Abstract:
The GdF 3 :Eu 3 + and NaGdF 4 :Eu 3 + powders were synthesized by hydrothermal method as raw material of Gd 2 O 3 , Eu 2 O 3 , NaF, NH 4 HF 2 , EDTA and polyethylene glycol. The powders were characterized by means of X-ray powder diffraction, SEM microscopy and Molecular fluorescence photometer. It was discussed that the pH value of aqueous solution had affection on the phase composition of synthesized powders. The complex fluorides GdF 3 and NaGdF 4 were synthesized in aqueous solution at the pH values between 3 and 6. The synthesized powders were single hexagonal phase of NaGdF4 crystal at pH=8. It was also found that different fluorescence properties were exhibited by Eu 3 + doping powders synthesized at different pH values of aqueous solution. The synthesized powders of GdF 3 and NaGdF 4 were excellent fluorescence materials.
