| Abstract: | SrLa2Al2O7 and SrGd2Al2O7 belong to the structural type Sr3Ti2O7. In SrGd2Al2O7 strontium and gadolinium occupy respectively the 12 and 9 coordinated sites, whereas in SrLa2Al2O7 the homologous cations are statistically distributed. The fluorescence spectra of both phases activated by Eu3+ ions show that the only possible position of Eu3+ is the 9 coordinated site. |
