The amount of copper in the copper sulphide layer and the amount of silver in the modified sulphide layer increased with the prolongation of the period of sulphurization in a polythionic acid solution and also of the treating time of the sulphurized sample in a solution of copper salts. X-ray diffraction results showed various copper sulphides, sulphur, silver, and silver sulphide in the samples. Silver sulphide and silver were formed when ion-exchange and reduction–oxidation reactions took place. A simple route to obtain copper and silver sulphides on polyethylene film is reported.
