Abstract

This paper presents the synthesis of pure and europium-doped lutetium oxide (Lu₂O₃) powders prepared by sol-gel method. The influence of europium ion concentration into Lu₂O₃ nanocrystallites was investigated for first time in an in vitro system using a modified ABTS radical cation decolorization assay to determine the antioxidant activity. The crystalline structure of Lu₂O₃ and Eu:Lu₂O₃ powders was elucidated by XRD obtaining cubic phase in all system without secondary products in accordance with FT-IR results. By TEM and Scherrer equation, it was determined that Lu₂O₃ and Eu:Lu₂O₃ powders presented nearly spherical particle morphology with crystallites sizes in the range of 8 to 13 nm. The antioxidant assays results revealed that europium ion enhance Lu₂O₃ powders antioxidant properties, showing that 12.5 mol% of europium is sufficient to reach its maximum capacity.
