Abstract

Spherical-like Tb 3+ and Eu 3+ co-doped Gd 2 O 3 nanoparticles with a particle size around 5.5 nm were synthesized by a polyol route. The optimized luminescence property was obtained when 5 mol% Tb 3+ and 2 mol% Eu 3+ were co-doped. The influence of different polyalcohol solvents (DEG/PEG) on particle size and luminescence properties was investigated. The results show that the nanoparticles Gd 2 O 3 :5%Tb 3+ prepared in PEG presented greater particle size (around 79 nm) and higher luminescence intensity. [ABSTRACT FROM AUTHOR]
