Summary:In this work, the preparation of cadmium telluride (CdTe) nanoparticles by aqueous solution method is presented. The preparation process was performed in the presence of an acidic agent (L-cys) at certain pH value. The x-ray diffraction (XRD) patterns and scanning electron microscopy (SEM) of the prepared samples showed that poly crystalline structure with lowest particle size can be produced by controlling the period of heating process after the preparation step. Accordingly, this parameter can be used carefully to control the surface roughness of nanoscale CdTe samples to serve certain applications requiring some determined values of particle size and surface roughness.
