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

while the broad band is resulted from impurity.
