 Abstract
Diffusion coefficient of Fe in polycrystalline host ZnSe as a mid-IR gain medium has been measured in the annealing temperature ranges of 850 to . The synthesis of the samples was carried out in quartz ampoule in which the Fe thin film deposited by physical vapor evaporation method on the ZnSe. One can realize that the diffusion coefficient strongly depends on the surface active surfactants through the cleaning process and the substrate temperature during the thin film deposition leading to for . The Annealing temperature dependence of the Fe ions diffusion in ZnSe was used to evaluate the activation energy, =1.39 eV for diffusion and the pre-exponential factor of .
