Color Dependence on Thickness in Topaz Crystal from Brazil
Table 2
Best-fitted parameters of the optical absorption spectra of thin sample of topaz heated at 200°C for Gaussian line shapes. The Gaussian amplitudes are given in absorbance units.

The amplitude values for which the errors are indicated by “?” are very small and therefore they could not be evaluated. These lines were maintained to give stability to the optimization algorithm used in the determination of the parameters of the lines. |
