I have been looking the way to coat metallic films of silver and nickel on glass substrate using spray pyrolysis method. But most literate shows the deposition techniques for metal oxides.
this is a very interesting technical question. In my experience it often pays off to search the "Publications" section of RG directly for helpful literature references about a certain research topic. For example, please have a look at the following potentially useful article (for silver thin films):
Thin Film Preparation of Silver Nanoparticle by Homemade Spray Pyrolysis System
Article Thin Film Preparation of Silver Nanoparticle by Homemade Spr...
This interesting paper has been posted by the authors as public full text on RG. Thus you can freely download it as pdf file and print it out if required.
Interestingly, most related articles involving nickel describe the deposition of nickel oxide (NiO) thin films on glas substrates using spray pyrolysis.
