Abstract
- Abstract The present study reports the insertion of europium ions into the network of lithium lanthanum titanate, La 0.5 Li 0.5 TiO 3 , powders. The materials were prepared efficiently via the Pechini method and were characterized using thermogravimetric analyses, X-ray diffraction, high-resolution electron microscopy and photoluminescence spectroscopy. The results obtained demonstrate the high structural disorder of La 0.5 Li 0.5 TiO 3 (LLTO) as well as the different environments noticed by Eu3+ ions in the La 0.5 Li 0.5 TiO 3 host lattice. Our results are essentially important once they unfold a better understanding of the complex nature of La 0.5 Li 0.5 TiO 3 compounds structure. [ABSTRACT FROM AUTHOR]
