Changes induced in the luminescent emission of Eu3+ by different crystal nature: An analysis by group theory

Abstract The effects of the crystal nature on the luminescent emission of Eu 3+ ion in Y 2 O 3 , HfO 2 and ZrO 2 oxides, synthesized by the hydrothermal route are reported. The luminescent spectra at room temperature, showed the peaks associated with the characteristic transitions of Eu 3+ ion, observing significant changes in the electric dipole transition 5 D 0 → 7 F 1 (D°→D 1 ), in each of the different crystals; the analysis by group theory allowed us to offer an explanation of the differences presented in the emission spectra in the different crystals.
