摘要

用发射、激发、时间分辨光谱和荧光衰减曲线测量

研究了玻璃基质中ZnSMn

纳米晶的荧光瞬态行为。发现材料中的389nm和404nm的蓝色发射不是通常报导的D-A对自激活发光

而是Mn

的间隙态引起的变化的自激活发光。这与我们前面的光谱和EPR谱实验结果是一致的。这种发射与Mn

间无能量传递。与ZnSMn

体粉末相比Mn

的

的跃迁荧光寿命明显变短。这说明由于量子限域效应

在纳米晶中ZnS向Mn

能量传递速度加快

另外表面态为能量弛豫提供了有效的无辐射通道.

Abstract

The transient behavious of ZnS:Mn

nanocrystallites dispersed in Pyrex glasses were studied by emission

excitation

time resolved spectra and luminescence decays. It was found that blue emissions peaked at 389 and 404nm are not self activated luminescence due to D A pairs but the emission from Mn

located at the intersticial sites. This is in good agreement with the results of the previous EPR experiments. There are no energy transfers between this emission and Mn

ions. The lifetimes of

transition to Mn

ions were shortened compared with that of ZnS:Mn

bulk powder. It is suggested that the ratio of the energy transfer from ZnS to Mn

ions gets faster by quantum confinements and efficient radiationless channels provided by surface states.
