ION SYNTHESIS OF FE AND AG GRANULAR FILMS IN VISCOUS AND SOLID-STATE POLYMERS

We present the study of iron and silver granular films formed by impla ntation of 40 Ke V Fe+ and 30 KeVAg+ ions in viscous and solid state s ilicone polymers at different doses. The structural, magnetic and opti cal properties of synthesized metal films were investigated by TEM, ma gnetic resonance and absorption UV-VIS spectroscopy methods. The TEM m icrographs of the iron films showed that the process of metal film gro wth in a polymer volume, the film morphology and the structure depend on the relaxation state of the silicone target. The dose dependencies of magnetic (effective magnetization) and optical (plasma resonance pe ak positions) parameters of the iron and silver films synthesized both in viscous and in solid polymer matrices are presented. The comparati ve analysis of the above dependencies showed that the method of ion sy nthesis of metal films in viscous silicone media provides a higher deg ree of coagulation of implanted ions in metal phase than that in solid state polymer.
