(Cu₆PS₅Br)₁₋ₓ(Cu₇PS₆)ₓ and (Cu₆PS₅Br)₁₋ₓ(Cu₇PS₆)ₓ mixed crystals were grown using a direct crystallization technique from the melt. Refractive indices and extinction coefficients for mixed crystals were obtained from the spectral ellipsometry measurements. A nonlinear increase in the refractive indi...
