| Abstract: | The luminescent properties of Tb~(3+) in rare earth orthoborates LnBO3(Ln=Y, Gd and La) under VUV excitation were studied. From Y-Gd-La. with the increasing of the canon radii and the lowering of the lattice symmetry, the lowest 4f75d levels of Tb~(3+) hift to higher energy. The influence of the concentration of Tb~(3+) on the emission of Tb~(3+) and the energy transfer between Ce~(3+) and Tb~(3+) in LaBO3: Ce, Tb were discussed too. It was found that the emission of Tb~(3+) in LaBO3: Ce, Tb is enhanced by Ce~(3+) when excited by UV, but it is killed by Ce~(3+) when excited by VUV. The experiment results show that LaBO3; Tb will be potential green phosphorus excited by VUV radiation. |
