We report on the sputter deposition of copper oxide sulfides Cu 2 O 1– x S x up to a composition of Cu 2 O 0.61 S 0.39 . For higher sulfur contents the films first become amorphous and then change to Cu 2 S. Within the range 0 < x < 0.39 the cubic crystal structure is maintained and the lattice constant changes linearly with the sulfur content. The composition of the films is measured by energy dispersive X‐ray fluorescence and suggests the formation of a random alloy. The transmission spectra show a clear red shift of the order of 450 meV (from Cu 2 O to Cu 2 O 0.61 S 0.39 ) with an average transmission of 70%. (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
