ABSTRACT:
The invention relates to the deposition of thin silver films on various substrates, particularly superconductor substrates. The method consists of CVD deposition of silver on a substrate with the aid of a silver precursor solution. The silver precursor is an RCO2Ag silver carboxylate, wherein R is a linear or branched radical having 3-7 carbon atoms, used in the form of an organic liquid solution. The precursor concentration of the solution ranges from 0.01 to 0.6 mol/l. The organic liquid comprises an amine and/or a nitrile and, optionally, a solvent whose evaporation temperature is lower than the decomposition temperature of the precursor. The percentage by volume of the amine and/or nitrile in the organic liquid is more than 0.1%.
