A series of new luminescent phosphors SrMgSi2O6:Ce,Tb have been prepared by a solid state reaction method. The phase characterizations, luminescence emission and excitation spectra and optimum doping concentrations of the SrMgSi2O6:Ce,Tb phosphors are investigated in detail. The intense green emission monitored at 542 nm is realized in the SrMgSi2O6: Ce, Tb phosphors on the basis of the highly efficient energy transfer from Ce3+ to Tb3+. The energy transfer mechanism is ascribed to the dipole-dipole interaction. When the Tb3+ ion concentration was increased to 0.05, the transfer efficiency increased to 77%. The critical distance of the energy transfer has been calculated by the concentration quenching method. (C) 2013 Elsevier B.V. All rights reserved.
