The absorption spectra of thin films of ZnI₂ and K₂ZnI₄ layered compounds intercalated with CO₂ molecules have been investigated in temperature interval from 90 to 240 K. It is found that the intercalation results in high-frequency shift of exciton bands and their broadening. Considering the structu...
