| Summary: | This study aims to prepare cadmium sulfide nanoparticles in two methods, which are the chemical method and the biological method using two types of extracts, green tea, and starch. The prepared nanoparticles were characterized by various techniques such as X-ray diffraction (XRD), scanning electron microscope (SEM), and Energy Dispersive X-ray Spectroscopy (EDX). The synthesis of crystalline CdS nanoparticles was confirmed by various analytical techniques such as X-ray diffraction (XRD) and the pattern reveals cubic and hexagonal structures. The average crystal size for the methods respectively is 11.5, 15.9, and 5.67 nm, which have a spherical shape for nanoparticles CdS by scanning electron microscopy (SEM). The peaks of cadmium and sulfur emerged in the assay (EDX). The energy gap of the CdS has increased than the energy gap of the bulk CdS, the results were 2.63, 2.88, and 3.06 eV, respectively. This is an evidence of obtaining a nano-material for CDS by these two methods.
