Abstract
A colored substrate and a method for producing a substrate having a colored interference filter layer containing a polycrystalline metal oxide or polycrystalline metal oxides with the aid of physical or chemical vapor deposition using a coating system, in particular with the aid of a sputtering gas, in which at least two, in particular at least six, coating layers are vapor deposited one on top of the other forming polycrystalline metal oxides in each case.
Claims9
A method for producing a substrate having a colored interference filter layer containing at least one polycrystalline metal oxide, comprising:
- vapor depositing at least six coating layers one on top of the other, polycrystalline metal oxides being formed in each of the at least six coating layers, wherein each layer of the at least six coating layers has an average thickness in a range of 50 nm to 350 nm, an averaged percentage atomic quantities of at least one of the metals contained in each of at least two coating layers deviating by no more than +/20 atomic percent, from an averaged percentage composition of the metals in the interference filter layer, 100 atomic percent being a sum of all metals contained in the layer.
