An optical study of silver particles fabricated by ion implantation in a silicon polymer

Polymer layers containing Ag were fabricated by 30 keV Ag-ion implantation into viscous and solid-state silicone organic matrices. The optical properties of the composites are presented by means of transmission spectra in the range from 250 to 870 nm for different ion doses of 0.05- 1.8 1017 ions cm...

Description
Summary:Polymer layers containing Ag were fabricated by 30 keV Ag-ion implantation into viscous and solid-state silicone organic matrices. The optical properties of the composites are presented by means of transmission spectra in the range from 250 to 870 nm for different ion doses of 0.05- 1.8 1017 ions cm-2. The absorption at the wavelength of the surface plasmon resonance of Ag particles at doses higher than 1016 ionscm-2 was determined. A remarkable red shift in the absorption maximum from 405 to 505 nm was observed with increasing dose and with a change in the viscosity of the irradiated polymer. The optical spectra of the implanted polymer were analysed using the Maxwell-Garnett effective-medium theory. The dose dependences of the calculated value of the metal volume fraction in the implanted polymer suggest the possibility of achieving a higher degree of coagulation of introduced metal ions to metal particles in a viscous polymer than in a solid-state matrix.
