Abstract

Novel blue-emitting phosphors Ca2SiO2F2:xCe3+ were synthesized by a solid state reaction technique at high temperature, and the luminescence properties were investigated in detail. The Ca2SiO2F2:xCe3+ phosphors show intense absorption at UV region and exhibit blue emission at ~ 455 nm under 365 nm excitation. The quenching concentration of Ce3+ in Ca2SiO2F2:xCe3+ phosphors is about 1 mol%. The results indicate that the Ca2SiO2F2:0.01Ce3+ phosphor has a potential application in white light emitting diodes (w-LEDs)..
