Abstract
The characteristics of the optical absorption of copper-activated zinc-sulfide polycrystalline layers after preliminary heat treatment are investigated. The composition of the compound under study was monitored by X-ray fluorescence analysis. The band gap Eg and characteristic Urbach energy are estimated from the fundamental absorption edge. The contribution of structural defects and the impurity factor to the variation in the optical properties is discussed.
