Luminescence properties of tunable red-green emitting phosphor Ba_2Ca（BO_3）_2：Eu~（3＋）,Tb~（3＋）

A series of Eu~（3＋） or Tb~（3＋） doped Ba_2Ca（BO_3）_2 phosphors were synthesized by a high temperature solid state method, and the luminescence properties are investigated. Ba_2Ca（BO_3）_2：Tb~（3＋） can show an obvious green emission, and the peak locates at 551 nm, which corresponds to the 5D34→7F5 tran...

Summary:A series of Eu~（3＋） or Tb~（3＋） doped Ba_2Ca（BO_3）_2 phosphors were synthesized by a high temperature solid state method, and the luminescence properties are investigated. Ba_2Ca（BO_3）_2：Tb~（3＋） can show an obvious green emission, and the peak locates at 551 nm, which corresponds to the 5D34→7F5 transition of Tb~（3＋）. Ba_2Ca（BO_3）_2：Eu＋ can present the characteristic emission of Eu~（3＋）, and the peak locates at 600 nm, which is ascribed to the 5D70→F2 transition of Eu~（3＋）. In order to achieve the emission-tunable phosphors, the Eu~（3＋）/Tb~（3＋） co-doped Ba_2Ca（BO_3）_2 are synthesized. When tuning the Eu~（3＋） or Tb~（3＋） concentration, Ba_2Ca（BO_3）_2：Eu~（3＋）, Tb~（3＋） can both show the tunable emission, which may be induced by the energy transfer from Tb~（3＋） to Eu~（3＋）.
