Abstract: A light-absorbing layer system includes an absorber layer having an oxidic matrix. The oxidic matrix is based on a base component made of zinc oxide, tin oxide and/or indium oxide, and on an added component which can replace the base component K1 up to a fraction of 75% by weight. The added component consists of niobium oxide, hafnium oxide, titanium oxide, tantalum oxide, vanadium oxide, yttrium oxide, zirconium oxide, aluminum oxide and/or mixtures thereof. A blackening component, made of molybdenum, tungsten and alloys and mixtures thereof, is distributed in the matrix and is present either as metal or as substoichiometric-oxidic compound of the metal, such that the layer material has a degree of reduction which is defined by an oxygen content of at most 65% of the stoichiometrically maximum oxygen content. The weight fraction of the blackening component is in the range between 20 and 50% by weight.

Abstract: Planar or tubular sputtering targets made of a silver base alloy and at least one further alloy component selected from indium, tin, antimony, and bismuth accounting jointly for a weight fraction of 0.01 to 5.0% by weight are known. However, moving on to ever larger targets, spark discharges are evident and often lead to losses especially in the production of large and high-resolution displays having comparatively small pixels. For producing a sputtering target with a large surface area on the basis of a silver alloy of this type, which has a surface area of more than 0.3 m2 as a planar sputtering target and has a length of at least 1.0 m as a tubular sputtering target, and in which the danger of spark discharges is reduced and thus a sputtering process with comparatively high power density is made feasible, the invention proposes that the silver base alloy has a crystalline structure with a mean grain size of less than 120 ?m, an oxygen content of less than 50 wt.
