| Popis: | The principal optical constants no, κo, ne, and κe of the hexagonal crystal CdSe are determined in the wavelength region between 380 and 950 nm at room temperature. The minimum reflectivities and the corresponding Brewster angles of parallel polarized light are measured for ordinary and extraordinary rays in the wavelength region between 380 and 728 nm. At longer wavelengths (κo < 10−3) Brewster-angle measurements and transmission measurements were applied. A plot of the absorption coefficients αo and αe versus wavelength indicates deviations from a direct band-gap parabolic absorption dependence. |
