摘要
The structural and optical properties of DC Sputtered Cd2SnO4 thin Films have been reported. The structure of the films was analyzed by X-ray diffraction and atomic force microscopy (AFM). The optical constants (refractive index, n, and absorption index, k) of the as-deposited films have been obtained in the wavelength range 300-1800 nm by using spectrophotometric measurements at nearly normal incidence. The obtained absorption index, k, was used to estimate the type of optical transition for the as-deposited films. The single oscillator model and Drude model of free carriers' absorption have been used for the analysis of refractive index dispersion, in the normal dispersion range. (C) 2013 Elsevier B.V.
