摘要

本文研究了在紫外光激发下Tb

单激活和Tb

+Dy

共激活的LaBO

体系的发光性能和能量传递.结果表明

共存时

的发光强度远远大于无Dy

时的发光强度

证明Dy

对Tb

有敏化作用

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 Tb

or Dy

singleactivated and Tb

+Dy

co-activated LaBO

under UV excitation.The results show that the emission intensity of Tb

in Dy

+Tb

co-activated LaBO

is larger than that in Tb

single-activated LaBO

.It proves that Dy

sensitizes Tb

.The mechanism of Dy

energy transmission is the resonance transmission of poly-pole interaction.
