Determination of nonlinear refracxtive index of zirconium and CNTs doped iron oxide thin films

摘要

In this present work, we have determined the nonlinear refractive index of zirconium (1 %) and CNTs (2 %, SW) doped iron oxide thin films by the single beam Z- scan technique with He-Ne laser at wavelength 532 nm. The findings of our study were that zirconium and CNTs doped iron oxide thin films show better nonlinearity comparison to reported results. The effect of dopant CNTs (2 %, SW) was negligible on the nonlinearity of zirconium doped iron oxide thin film. The order of nonlinear refractive index was 10~(-8).
