| 摘 要： | 本文研究了在紫外光激发下Tb3+,Dy3+单激活和Tb3++Dy3+共激活的LaBO3体系的发光性能和能量传递.结果表明,Dy3+,Tb3+共存时,Tb3+的发光强度远远大于无Dy3+时的发光强度,证明Dy3+对Tb3+有敏化作用,Dy3+→Tb3+能量传递机理为多极子相互作用的共振传递.

| Abstract: | This paper studied the luminescence and energy transmission of Tb3+ or Dy3+ singleactivated and Tb3++Dy3+ co-activated LaBO3 under UV excitation.The results show that the emission intensity of Tb3+ in Dy3++Tb3+ co-activated LaBO3 is larger than that in Tb3+ single-activated LaBO3.It proves that Dy3+ sensitizes Tb3+.The mechanism of Dy3+→Tb3+ energy transmission is the resonance transmission of poly-pole interaction. |
