Gd2O3 nanoparticles were synthesized by using our original method for application as MRI contrast agents. The sample diameters were controlled in the range 18-66 nm by adjusting the annealing temperature between 773 and 1273 K in air or in an Ar atmosphere. Magnetization measurements were performed at 300 K, and the effective magnetic moment of each sample was calculated. They showed paramagnetism at 300 K and they had large effective magnetic moment μeff of 7.15-8.05 μB. MRI measurements were performed in 0.8 wt% agarose solution, and the Gd 2O3 nanoparticles were found to work as effective T 1-shortening MRI contrast agents.
