Abstract

In the present work, Cu-doped ZNSE Nanocrystals (NCs) synthesized for 5, 10 and 15 min illumination times and different concentrations of impurity by PHOTOCHEMICAL method. XRD and TEM analysis demonstrated zinc blende phase NCs with an average size of around 3nm. UV-Vis analysis showed the band gap of ZNSE NCs decreased from 3.8 to 3.45eV for 5 to 15 min synthesis time. PL spectra of ZNSE NCs showed a broad emission with two peaks located at 380 and 490 nm related to exitonic and trap states emission, respectively. For ZNSE: Cu NCs, exitonic emission decreased and PL intensity of trap states emission increased by increasing the synthesis time so that after 10 min, exitonic emission quenched completely and trap states emission reached to its maximum value.
