Abstract
By identifying a suitable concentration ratio of salt/citric-acid/urea, we demonstrate that homogeneous precipitation in the presence of a citric acid capping agent can be used to synthesize spherical Eu:La2O3 precursor (p-Eu: La2O3) nanoparticles with a (375 +/- 60) nm diameter. Subsequent calcination of the precursor yields crystalline Eu:La2O3. We use the same synthesis technique to prepare various core/shell nanostructures such as p-Eu:La2O3/p-Tb:Y2O3, SiO2/p-Eu:La2O3, and p-Tb:Y2CO3/p-Eu:La2O3. In the absence of citric acid, we obtain one-or two-dimensional nanostructures. (C) 2014 Elsevier B.V. All rights reserved.
