【Abstract】 In this paper, a nonlinear regression model is utilized to measure the optical constants of TiO 2 thin film. We measured the optical constants by fitting the visible transmission spectra. The results suggest that this method can be applied to estimate optical constants, such as dispersion refractive index, thickness and absorption coefficient effectively for its versatility.更多还原
