Synthesis and Luminescent Properties of Terbium(III) and Europium(III) Fluoride Nanoparticles Modified with Aromatic Carboxylic Acids

Abstract

Europium(III) and terbium(III) fluoride nanoparticles modified with citric, anthranilic, benzoic, salicylic, and acetylsalicylic acids have been obtained by means of sorption from solution and modification in statu nascendi. The shape and size of the particles have been determined by scanning electron microscopy. The luminescence of the samples was studied and it has been established that terbium fluoride nanoparticles modified with acetylsalicylic acid exhibits the highest luminescence intensity.
