Abstract

In the present work, the complex refractive indices have been determined for thin films of zinc over the ranges from 1.55 to 4 eV and from 2.5 to 40 µm, using a transmission method. The experimental results have been compared with theoretical structure of zinc. The direct transmission spectrum of zinc thin films deposited on different substrates has been measured at 300 K. All films prepared for optical measurements, were deposited at pressure 10-4 Pa, with deposition rate of 2.5 nm/s. The measurements were made using a Beckman Double Beam Spectrophotometer IR-4220 and UV-5203 in the infrared and visible region, respectively.
