Beschreibung
Zusammenfassung:	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 E g 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.
