Synthesis and Spectroscopic Studies of Copper Selenide Nanoparticles

Copper selenide nanoparticles were synthesized using solvothermal route at different temperatures using ethylenediamine as a solvent. The study of the molecular structure by FTIR spectroscopy indicated that the cupper complex with ethylenediamine through the nitrogen atom was formed when the sample prepared at 140 °C. The cupper selenide nanoparticles were formed at temperatures 160, 170 and 200 °C. The X-ray diffraction data revealed that, all samples exhibit crystalline nature and the particle size depends on the temperature. At the same time transmission electron microscope was used in studying of the morphology and particle size. The particle size estimated by XRD and TEM was consistent and the two in nanorange. The obtained results reveal that the CuSe nanoparticles were formed with particle size 13, 15 and 21 nm at temperatures 160, 170 and 200 °C respectively
