| Abstract: | The luminescence properties of undoped and Fb2+-, Tb3+-, and Ce3+-doped BaLaGa3O7 have been studied. At LHeT undoped BaLaGa3O7 shows an emission with a maximum at 490 nm. The emission of Ba0.99Pb0.01LaGa3O7 consists of a broad band with a maximum at 400 nm, that of BaLa0.89Tb0.02Ga3O7 of the well-known 5D3 and 5D3 Tb3+ emission lines. The last compound shows a strong afterglow. BaLa0.98Ce0.02Ga3O7 did not luminescence; a possible explanation is presented. |
