Willi,

Since there are no blue elements nor (as far as my chemistry goes) any blue simple compounds such as oxides, nitride, fluorides, carbides, etc. preparing a blue layer by normal or reactive sputtering may not be possible.

I suspect most blue colors are the result of light adsorptions/reflections in some fairly large molecular structures (even copper sulphate isn't blue without its 6 water molecules). Sputtering is pretty could at breaking molecules into atomic species and not necessarily rearranging them correctly on the substrate. For example, the only polymer I know that is successfully sputtered is PTFE in which the "molecule" that's transferred from target to substrate is CF2.

One company selling targets in Europe is the Lesker company in Hastings UK and Budapest, Hungary. Contact international@lesker.com and they'll forward you to the right people.
