摘要

我们测量了被Al

隔离层与Ag

和SnO

表面分隔开的噻吩甲酰三氟丙酮铕〔europium(Ⅲ)thenoytrifluoroacetonate

EuTTA〕分子的荧光强度。实验结果显示当隔离层厚度为1～10nm时

由于非辐射能从发射中心Eu

离子传输入介电界面

荧光强度随隔离层厚度减少按指数式减弱。这与能通量模型理论结果相符合.

Abstract

Distance-dependent fluorescent intensities emitted by europium(Ⅲ) thenoytrifluo roacetonate(EuTTA) molecules separated from Ag

and SnO

interfaces by Al

spacer has been measured. The results show that as the spacer thickness is in range of 1~10 nm

due to the nonradiative energy transfer from the emitting center Eu

ions to the dielectric interfaces

the fluorescent intensities vary with the spacer thickness exponentially

and that this is in agreement with the energy flux model.
