Abstract :
The crystals CdI2 activated by gold and copper were investigated. It was shown that activated by gold and copper samples CdI2:Au,Cu are optically resistant to high-energy electromagnetic radiation. Also the Cu-doping effects in CdI2 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.
