Abstract
In the present work, Cu-doped ZnSe Nanocrystals NCs were synthesized by a simple photochemical method. XRD and TEM analysis demonstrated zinc blende phase NCs with an average size of around 3 nm. UV-Vis analysis showed decreasing the band gap of ZnSe NCs from 3.80 to 3.45 eV for 5 to 15 min illumination time. Photoluminescence spectra of ZnSe NCs showed a broad emission with two peaks located at 380 and 490 nm related to excitonic and trap states emission, respectively. For ZnSe:Cu NCs, excitonic emission was decreased and PL intensity of trap states emission increased and for 10 min illumination, excitonic emission quenched completely and trap states emission reached to its maximum value.
