Abstract
The preparation of fibrous and spheroidal nanonstructured composites o f gamma-alumina matrices impregnated with Eu2O3 together with their ph ysico-chemical morphology are described. The emission properties of Eu 3+ ion were investigated in both nanocomposites. A more intense emissi on in the spheroidal nanocomposite than in the fibrous has been found. In addition to the Eu3+ emission two broad emission bands centered at 770 and 500 nm were observed. These latter are inherently associated with porous alumina matrices.
