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 ...

The paper is a brief review of optical properties of nanostructures containing metal nanoparticles. There is a deduction of some simple formulae describing optical spectra of composites containing small particles of various ...

A setup for observation of the nonlinear self-diffraction effect has been described. A semiconductor laser (P≈50 mW, λ≈660 nm) is used as a radiation source. The laser beam is divided into two beams by a Wollaston prism, ...
