Abstract
A process for producing a deposit of an inorganic and amorphous protective coating on an organic polymer substrate, the coating comprising compounds in the form of an oxide, nitride, carbide, or alloys thereof, by photosensitized decomposition in the gas phase, which comprises decomposing a gas medium by photosensitized decomposition, including precursors of the elements constituting the deposit of the inorganic and amorphous protective coating to be produced by photonic excitation of an impurity which has been previously introduced into the medium, said decomposition being adapted for producing an indirect transfer of energy to the molecules of the medium, thereby causing the decomposition and subsequent deposition of the these elements onto the substrate.
