EuxLa1 - xTa7O19 geptatantalates have been synthesized (x = 0.005-10). The luminescence and excitation spectra of these geptatantalates have been investigated at 77 and 300 K. It is supposed that the Eu3+ luminescence spectrum for all x may be interpreted within one type optical center with D2d symmetry. The energy level diagram of the luminescence center has been worked out. It has been found that there is concentration dependence quenching of an europium luminescence. The reasons for this are discussed.
