Luminescent and Photocatalytic Properties of BaCoF₄: Ce³⁺ Synthesized by Reflux Method

Abstract:

The complex fluorides BaCoF₄ and BaCoF₄: Ce³⁺ were synthesized by reflux method in ethylene glycol and characterized by means of XRD, TEM, XPS, UV-VIS and Fluorescence Spectrophotometer. In addition, the photocatalytic degradation property of BaCoF₄: Ce³⁺ was investigated. The results indicated that the mean particle diameter of BaCoF₄ was 54.6 nm. Only adsorption oxygen (α oxygen) existed on the surface of BaCoF₄ and the content of surface oxygen was 5%. The BaCoF₄: Ce³⁺ had a stronger absorption at 250 nm, which could be explained by d electronic transition of Ce³⁺. The maximum emission peak of BaCoF₄: Ce³⁺ was 361.8 nm in its luminescent spectrum, and emission band of Ce³⁺ belonged to 5d4f transition. Meanwhile, the degradation rate of acid red 3B by BaCoF₄: Ce³⁺ reached 98.7% after being lightened for 2 h by a 450 W high pressure mercury lamp.
