Abstracts

EN

Cu and Fe doped cadmium sulfide nanoparticles with controllable and relatively narrow size distribution were prepared using a facile and efficient wet chemical route by mixing the reactants in water solvent. It was found that the mixture pH plays an active role in the growth procedure of nanoparticles. Diverse physical properties of the prepared nanoparticles were investigated using UV-vis absorption, photoluminescence spectroscopy, scanning electron microscopy, transmission electron microscopy and energy dispersive X-ray spectroscopy. The average particle size of samples was estimated to be about 5 nm by using transmission electron microscopy measurement. The pH optimization study implies that pH ≈7 would yield an enhancement in photoluminescence intensity. There are two bands in photoluminescence spectra which related to deep and shallow traps.
