| dc.description.abstract | Undoped and doped KCl single crystals by CdSe nanocrystals (NCs) have been grown by Czochralski (CZ) method with pulling rates in the 8-10 mm/h range. The crystals thus obtained were cleaved into samples of required size. The structural investigation of these samples has been deduced from Ө-2Ө (XRD) and Raman spectroscopy. The nano-size of CdSe aggregates in KCl host determined from XRD measurements by using the Sheerer formula. The Raman spectroscopy presented the LO mode vibration relative of (Cd-Se) chemical liaison. Moreover, the results of the optical absorption and photoluminescence spectra confirmed the nano-size of CdSe aggregates were observed band absorption located at 622,5nm relative of electronic transition 1se-1s3/2 of CdSe, with a blue shift from the bulk gap of ΔEg=0,26eV (Eg (CdSe) bulk=1,73eV), while the photoluminescence showed a band situated at 643, 55 nm, with displacement Eg towards the short wavelength (blue shift), this bleu shift due to the nanometric size of CdSe aggregates. | ar |
