Abstract
In this work, cadmium sulfide nanoparticles were synthesized with different sizes by chemical precipitation
method. Transmission electron microscopy (TEM) and X-ray diffraction pattern (XRD) used to study the
morphologies, distribution, and crystallinty of the CdS nanoparticles and to calculate the values of their sizes.
The results indicated that the CdS were formed with cubic structure and the particle size decreases with
increasing the Cd+2 ions. The Cd-S stretching vibration band appeared in the far infrared region at about 250 cm-
1 and there is no effect of the particle sizes on the position of this band. Dependence of the blue shift and optical
band gap on the quantum size effect was confirmed by UV-Visible spectroscopy. The dielectric properties are
studied in the frequency range (2.5 KHz-5MHz) at different temperatures.
