Optical and luminescence effects in Cu, Au-doped cadmium iodide layered nanostructures

The crystals CdI
₂
activated by gold and copper were investigated. It was shown that activated by gold and copper samples CdI
₂
:Au,Cu are optically resistant to high-energy electromagnetic radiation. Also the Cu-doping effects in CdI
₂
layered nanocrystals were studied experimentally. We used a photostimulated second harmonic generation (PSHG) in order to investigate the nanoconfined effects. It was found that the PSHG increased with increasing Cu-doping within a lowdensity limit.
