The phosphors Sr3B2O6: Ce3+, Sr3B2O6: Tb3+ and Sr3B2O6: Ce3+, Tb3+ were synthesized by the solid-state reaction method at high temperature. For the phosphor Sr3B2O6: Ce3+, the lowest 5d levels, the emission and the Stokes shifts of Ce3+ in the host lattice were identified. In addition, its concentration quenching process was also studied. For the phosphor Sr3B2O6: Tb3+, the f-d transitions of Tb3+ in the host lattice were assigned and discussed. Moreover, the energy transfer phenomenon between Ce3+ and Tb3+ in Sr3B2O6: Ce3+, Tb3+ was discussed. The emission of Tb3+ is significantly enhanced due to energy transfer from Ce3+ to Tb3+ when Ce3+, Tb3+ dopants were used together in Sr3B2O6.
