Abstract
The complex fluoride BaNiF4:Ce3+ was synthesized by reflux method using ethylene glycol as reaction solvent at its boiling point temperature. The sample was characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and fluorescence spectrophotometer. The results indicated that the mean particle diameter of BaNiF4:Ce3+ was 53.8 nm. Only adsorption oxygen (α oxygen) existed on the surface of BaNiF4: Ce3+ and the content of surface oxygen was ≤5%. The maximum emission peak of BaNiF4:Ce3+ was 350 nm in its luminescent spectrum, and emission band of Ce3+ belonged to 5d→4f transition.
