Abstract

The effect of mechanical alloying on the photoluminescence behavior of gamma-Al2O3 nanopowder was studied. Two emission peaks centered at 343 and 378 nm and a broad emission band ranging between 400-600 nm have been observed. It is found that the intensity of the two emission peaks decreases with ball-milling time, while that the broad band remains un-change. 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.
