Synthesis, Characterization and Optical Property of KLaF₄:Ce³⁺ Nano Particle

Abstract:

Ce³⁺ doped cubic KLaF₄ system was synthesized by co-precipitation method. The sample was characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), UV-Vis spectrophotometer and fluorescence spectrophotometer. The result indicated the nanoparticle diameter of KLaF₄:Ce³⁺was 12.5 nm. The KLaF₄:Ce³⁺had a stronger absorption at 250 nm, which could be explained by d elecronic transition of Ce³⁺. The maximum emission peak of KLaF₄:Ce³⁺was 355 nm in its luminescent spectrum, and emission band of Ce³⁺ also belonged to 5d→4f transition.
