Investigation of the transformation of the surface architecture of zinc oxide powders synthesized by grinding during etching with argon ions
Abstract
Purpose: The aim of the work is to study by X-ray photoelectron spectroscopy the transformation of the surface architecture of zinc oxide powders, previously obtained by mechanical milling, during their etching with argon ions.
Experimental: The etching was carried out in two steps of 30 s duration each at a current of 1 μA. It was found that on the surface of initial powders 45 % of zinc is a part of the crystal lattice of ZnO, and the remaining 55 % exist in the form of hydroxide.
Conclusions: The first etching step reduced the fraction of hydroxyl groups on the surface to 1 per 5 zinc cations in the ZnO lattice, and further etching showed the impossibility of deeper purification of the sample from OH-groups. In contrast, the carbon atoms almost completely left the powder surface after the end of the second etching step
