Abstract In the present paper, Ce3+ and Eu2+ co-doped silicate Ba2SiO4∶xCe3+,0.02Eu2+ green-emitting phosphors were synthesized by conventional solid-state reaction in a CO-reductive atmosphere. The diffuse reflection spectra, excitation spectra, and emission spectra of Ba2SiO4∶xCe3+, 0.02Eu2+ were measured and studied. Due to the good overlap between the Ce3+ emission bands and the Eu2+ excitation bands, the energy transfer between Ce3+ and Eu2+ is expected to be very efficient and is confirmed by the emission spectra of Ba2SiO4∶xCe3+,0.02Eu2+. Co-doped Ba2SiO4∶xCe3+,0.02Eu2+ is efficient green phosphors with the excitation of longer wavelength UV light, and the emission intensity is stronger than Eu2+ doped Ba2SiO4 phosphors. Analyzing the spectra, the authors draw a conclusion that the luminescence sensitization of Eu2+ by Ce3+ in Ba2SiO4∶xCe3+, 0.02 Eu2+ is due to the efficient energy transfer from Ce3+ to Eu2+ under long UV light.
