Preparation of luminescent Y2O3: Eu3+, Tb3+ nanoparticles and nanostructures by polyol mediated synthesis

The materials on nanosized dimension exhibit properties that can be significantly different from their massive counterpart, for this reason the increasing investigation developed in this domain continues advancing. Tb3+ and Eu3+ doped Y2O3 in the nanoscale size were obtained by the polyol mediated synthesis. This work presents a general view of nanoparticle synthesis and the aggregation of the same, in order to form nanostructured materials with luminescent properties. Nanometric and nanostructured materials were evaluated by luminescence spectroscopy where the emission spectra observations for the two materials show high similarity. These observations confirm on the one hand that Tb3+ and Eu3+ ions are located in the Y2O3 matrix, on the other hand that the aggregate material are constituted by nanoparticles with resembling size (5 nm).
