| Abstract: | In the paper the luminescent properties of Ce~(3+), Tb~(3+) and Mn~(2+) doped BaB_8O_1.are reported. In the octaborate the Ce~(3+)-Tb~(3+) energy transfer can be well describedbv a discrete model considering S-A and S-S transfers. Under UV excitation, the redand the green luminescence bands are observed in Ce~(3+) and Mn~(2+) codoped octabora-te. The former is attributed to the Mn~(2+) centers which are located at tetrahedral si-tes and the latter is assigned to the Mn~(2+) ions which are situated in octahedral posi-tion. The Ce~(3+)-Mn~(2+) energy transfer is discussed as well. |
