Abstract
The physico-chemical environment around the aluminum impurity atoms in commercial Herasil silica is studied by electron-induced X-ray emission spectroscopy. Despite the low concentration of aluminum and the charging effect occurring upon electron irradiation , we have been able to characterize the environment of the Al atoms. We show that the Al atoms are in an octahedral environment , i. e. surrounded by 6 oxygen atoms. The presence of Al clusters , whose metallic character would make them candidates to be ultraviolet absorption centers , is ruled out.
