Preparation and luminescence of europium-doped lanthanum fluoride–benzoic acid hybrid nanostructures

Add time:09/30/2019    Source:infona.pl

Europium-doped lanthanum fluoride (LaF 3 :Eu 3+ ) nanoparticles were synthesized using a solvothermal method, and they were then capped with benzoic acid (BA) ligands to form LaF 3 :Eu 3+ –BA hybrid nanostructures. The LaF 3 :Eu 3+ –BA hybrid nanostructures showed strong luminescence as a result of energy transfer from BA to the Eu 3+ ions of the LaF 3 :Eu 3+ nanoparticles. The dominant excitation band for the LaF 3 :Eu 3+ –BA hybrid nanostructures ranged from 200nm to 300nm. It has been shown that the luminescence of LaF 3 :Eu 3+ –BA hybrid nanostructures strongly depends on the pH value and content of benzoic acid used in the preparation of the hybrid nanostructures. An X-ray diffraction technique, transmission electron microscopy, luminescence spectroscopy, Fourier transform infrared spectroscopy and a UV–vis spectrophotometer were used to characterize the products.
