本文报道Ce~(3+)Tb~(3+)(或Mn~(2+))激活BaB_8O_(13)的发光性质。用层式分立模型解释了Ce~(3+)-Tb~(3+)能量传递过程。Mn~(2+)在八硼酸盐中的发射由绿色带和红色带组成,前者归于四配位Mn~(2+)的发射,后者归于八配位Mn~(2+)的发射。还对该体系中Ce~(3+)-Mn~(2+)能量传递作了讨论。
The luminescence properties of BaB_8O_ (13) activated by Ce ~ (3+) Tb ~ (3 +) (or Mn ~ (2+)) were reported. The layered discrete model is used to explain the energy transfer process of Ce ~ (3 +) - Tb ~ (3+). The emission of Mn 2+ in octaborate is composed of green band and red band, the former is attributed to the emission of the tetracoordinate Mn 2+ and the latter is attributed to the emission of octocompatibility Mn 2+. . The energy transfer of Ce ~ (3 +) - Mn ~ (2+) in this system was also discussed.
