Influence of Different Synthetic Methods on Morphology and Luminescent Properties of LaF3:Eu3+ Nanoparticles

Abstract

Fluorescent europium ion doped lanthanum fluoride (LaF₃:Eu³⁺) nanoparticles were synthesized using various methods which includes hydrothermal, co-precipitation and sonochemical method. A series of experiments were performed to obtain variations in the morphology, structure and optical behaviour of fabricated products. The optical and structural properties of the fabricated nanoparticles (NPs) were characterized through scanning electron microscopy (SEM), powder X-ray diffraction (PXRD), energy dispersive X-ray spectroscopy (EDS), Fourier transform infrared (FTIR) spectrometry, and particle size by dynamic light scattering (DLS). In LaF₃ nanoparticles, the existence of europium as dopant ions was confirmed through energy dispersive X-ray spectroscopy (EDS). The optical properties of the synthesized nanoparticles were investigated by conducting photoluminescence (PL) studies.
