Asst. Prof. Dr. Naghim Mohi Kadhim , Physics Department , faculty of Science has published a research in NanoWorld Journal of the United States of America.
The researcher indicates that her research deals with the preparation of nanometer-sized CdS particles using an environmentally friendly and low-cost method. This method relies on the use of parts of plants as reducing and protective agents, as well as the method of synthesis of CdS nanoparticles using avocado peel extract, which converts Cd2 + into Cd atoms and then Forming CdS nanoparticles, and studying the effect of pH, peel extract concentration and reaction time on the formation of the prepared CdS nanoparticles. The structural properties of CdS nanoparticles have been investigated using electron microscopy techniques (FE-SEM and TEM).
The study concludes that the majority of CdS particles are rectangular to spherical. The crystal structure of CdS nanoparticles (Face Center Cubic-FCC) is confirmed using X-ray diffraction, and the particle size is estimated from Scherer’s equation to be about 2.5 nm.
