• : cadmium selenide; electron microscopy; energy dispersive X-ray analysis (EDAX); semiconductor; Introduction In recent years, the synthesis and characterization of quantum dots and nanoparticles of group II-VI compound semiconductors have generated a great deal of research interest because of their

• synthesized cadmium selenide quantum dots was also confirmed by EDAX, as shown in Figure 8. It indicates the presence of cadmium and selenium, along with very small amounts of carbon and oxygen, probably due to incomplete removal of PVA. The areas of the peaks, after correction for the X-ray emission cross

• -section of Cd and Se, indicate the stoichiometry of the cadmium selenide quantum dots formed as 1:1, i.e., Cd1Se1. TEM and AFM studies Transmission electron microscopy and atomic force microscopy are very important techniques for providing information about particle size, shape, surface topography, etc
