Abstract

In this paper, we report a facile method for synthesis of ultra small (1-3nm) gadolinium oxide (Gd₂O₃) nanoparticles using citric acid (CA) as a capping agent. The dependence of nanoparticle (NP) size on the ratio between CA and gadolinium (Gd) is investigated. Absorption properties of the ultra small Gd₂O₃ NPs in UV region have four characteristic peaks at 312nm, 274nm, 253nm and 228nm. Finally, we show that the Gd₂O₃ nanoparticles synthesized by this method induce triplet emission (phosphorescence) from CA and EG in the NIR region.
