The absorption spectra of thin films of (KI)₁₋x(PbI₂)x 0.1≤ x≤ 0.5 were investigated in the spectral interval 2–6 eV. The formation of two compounds KPbI₃ and K₄PbI₆ in system KI–PbI₂ was determined on the basis of the spectra analysis. It was shown, that exciton excitations in the investigated comp...
