摘要

研究了机械球磨对γ-Al

纳米粉末的光致发光行为的影响。γ-Al

两个发射峰位于343

378 nm

同时我们观察到一个分布在400~600 nm 宽带发射。我们发现两个发射峰强度随着球磨时间的增加而降低

但宽带发射的强度不发生变化。这些结果证明

两个发射峰是由于类似F

心表面缺陷所致

而宽带发射是由于杂质所致。

Abstract

The effect of mechanical milling on the photoluminescence behavior of γ-Al

nanopowder was studied. Two emission peaks centered at 343 and 378 nm and a broad emission band ranging between 400~600 nm were observed.It was found that the intensity of the two emission peaks decreases with ball-milling time

while that of the broad band emission remains invarriable. These results suggested that the two peaks are resulted from the surface defects that analogs of F

centers

while the broad band is resulted from impurity.
