Outline of Final Research Achievements

We investigated the optical and electrical properties and considered the appropriate dielectric function for elucidating unique color phenomena in metal surface. In particular, we attended to sulfurizing of silver, application as a photoconductive sensor has been proposed in addition to the dielectric function model of the color layer. Reacting silver substrate and thin film with sulfide, we measured the optical properties and vilified the validity of the application of the thin-interference equation and Drude-Lorentz model. Moreover, we demonstrated photoconductivity of the sulfide silver nano-layer with transparency.
