Chemical Synthesis of CdSe Nanoparticles by using Hydrazine Monohydrate as A Reducing Agent

Cadmium selenide (CdSe) nanoparticles (NPs) is a low band gap material (Eg = 1.75 eV, at room temperature). II-VI semiconductor nanoparticles are currently of great interest for their practical applications in zero-dimensional quantum confined materials and for their applications in optoelectronics and photonics. In the present work, we have synthesized nanoparticles of CdSe by using chemical method. The synthesized CdSe NPs were well characterized by powder X- ray diffraction (XRD) and Field Emission Scanning Electron Microscopy (FE-SEM). It is investigated that as synthesized powder has a hexagonal structure of CdSe with diameters of the particles in the range of 74.68 nm. The FTIR spectra were used to identify the possible chemical-molecules responsible for the reduction of cadmium, selenide ions and reducing of hydrazine monohydrate formed CdSe NPs. Synthesized CdSe NPs were investigated at room temperature photoluminescence for excitation wavelengths 422 nm.
