Abstract

In the work, it is reported that morphological, electrical, and optical studies were conducted on nanoparticles of cadmium selenide (CdSe) that were synthesized using ethylenediaminetetraacetic acid (EDTA) as the complexing agent.The produced particles were characterized by using a transmission electron microscope (TEM), a field emission scanning electron microscope (FESEM), energy dispersive x-ray (EDX), and ultraviolet-visible spectroscopy (UV-VIS). The bandgap was discovered in the direct band, where it was estimated from the absorption. This gap is equal to 2.1 (eV). At various temperatures, the electrical properties of CdSe thin films were studied. A combination of dark electrical conductivity and photoconductivity indicates that these films can be used as photo sensors..
