一系列 Eu 3+ 或 Tb 3+ 做了 Ba 2 Ca (BO 3)2 黄磷被一个高温度固体状态方法综合,并且光性质被调查。Ba 2 Ca (BO 3)2:Tb3+ 能显示出明显的绿排出物,并且山峰在 551 点定位 nm,它对应于 5D 47 Tb 3+ 的 F 5 转变。Ba 2 Ca (Eu 3+, 和山峰的典型排放在 600 nm 定位的在场的 BO 3)2:Eu3+ 罐头,被归功于到 507 Eu 3+ 的 F 2 转变。以便完成排放悦耳的黄磷, Eu 3+/Tb3+ 共同做 Ba 2 Ca (BO 3)2 被综合。当调节 Eu 3+ 或 Tb 3+ 集中时, Ba 2 Ca (BO 3)2:Eu3+, Tb 3+ 能两个都显示出悦耳的排放,它可以被精力转移从 Tb 3+ 导致到 Eu 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 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+).
