Abstract
A series of Eu3+or Tb3+doped Ba2Ca(BO3)2phosphors were synthesized by a high temperature solid state method, and the luminescence properties are investigated. Ba2Ca(BO3)2:Tb3+can show an obvious green emission, and the peak locates at 551 nm, which corresponds to the 5D47F5transition of Tb3+. Ba2Ca(BO3)2:Eu3+can present the characteristic emission of Eu3+, and the peak locates at 600 nm, which is ascribed to the 5D0→7F2 transition of Eu3+. In order to achieve the emission-tunable phosphors, the Eu3+/Tb3+co-doped Ba2Ca(BO3)2are synthesized. When tuning the Eu3+or Tb3+concentration, Ba2Ca(BO3)2:Eu3+, Tb3+can both show the tunable emission, which may be induced by the energy transfer from Tb3+to Eu3+.
