Abstract

Using the Michelson technique we measured the refractive indices for the plane-parallel thin plates made of ${\mathrm{AgCl}}_{1-x}{\mathrm{Br}}_x(0\le \mathrm{x}\le 1)$ and, to the best of our knowledge, for the first time for the ${\mathrm{Ag}}_{0.95}{\mathrm{Tl}}_{0.05}{\mathrm{Br}}_{0.95}{\mathrm{I}}_{0.05}$ plate, manufactured by hot embossing, at 632.8 nm. We recorded their absorption spectra within the range of 0.19–41.67 μm using UV–Vis spectrophotometry and Fourier transform infrared spectroscopy, which demonstrated that the increase of substituent silver bromide or thallium monoiodide mole fraction in the corresponding solid solution causes the optical density to grow. As the result it moves the transmission edges toward longer wavelengths, while slightly reducing the transmission peak.
