In order to investigate optical properties of silver films with different film thickness, multilayer composed of thin silver film sandwiched between ZnS films are Sputtered oil the float glass. The crystal structures, optical and electrical properties of films are characterized by various techniques, Such as X-ray diffraction (XRD), spectrum analysis, etc. The optical constants of thin silver film are Calculated by fitting the transmittance (T) and reflectance (R) spectrum of the multilayer. Electrical and optical properties of silver films thinner than 6.2 nm exhibit sharp change. However, variation becomes slow as film thickness is larger than 6.2 nin. The experimental results indicate that 6.2 nm is the optimum thickness for properties of silver. (C) 2008 Elsevier B.V. All rights reserved.
