Abstract
The preparation, morphology and structural properties of Eu 3+-doped LaAlO 3 nanocrystallites based on Pechini's method is presented. The annealing temperature and Eu-ion content on the forming process of nanocrystallites is investigated. Preliminary studies on the size effect of the LaAlO 3 nanocrystallites on the luminescence properties of Eu-ions are done. The time resolved luminescence spectra and decays were recorded for powders characterized by a different size of grains. The effect of nanocrystallite sizes on the radiative relaxations of Eu 3+ luminescence was found.
