Popis: As an alternative to recording media on the tellurium base, recording media built in the form of matrix structures in which a photo(thermo)active component is included into the matrix can be used. We suppose that the most effective preparation method of such media which provides the deposition on substrates of any form can be a dissociation method of organometallic compounds (OMC). Depending on the choice of OMC, atmosphere in which occurs its decomposition, additions and conditions of process following there can be obtained by polymerization of OMC ligands in which is distributed a metal phase (metal-polymeric media) and an oxide matrix in which are implanted organic ligands changing its parameters. The gradient metal spreading was created by increasing the pulse amplitude of voltage discharge from 500 to 2000 V. The content of metal was increased in direction from substrate and was near substrate 0 - 10 at percent and near free film surface up to 80 at percent. The film composition was investigated by means of the layer-to-layer auger analysis using microscope JAMP-10 S. The comparative analysis of Raman spectra of starting OMCs and prepared from them films showed the advent of new bonds of the type metal-metal, carbon-carbon and the decrease of bonds quantity of the type carbon-carbon, metal-ligand. The action of focused laser radiation on such films leads to formation of microholes in the center of the irradiation region and on peripheral areas it leads to an additional OMC decomposition.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.
