Laser-Ablation Synthesis of Nanoparticles

The need for energy has reached a remarkable level that needs to be solved. In this study, nanoparticles of cuprous oxide (Cu 2 O) doped with varying amounts of samarium (Sm) were prepared by using solution precursor route approach with the aid of ultrasonic sound. Copper chloride and Samarium (III) Chloride was used as source for copper ions and samarium ions, respectively. X-ray diffraction (XRD) measurement confirmed that the prepared nanostructures are crystalline and the dopant Sm ion did not alter the crystalline structure of the Cu 2 O. The sample absorption spectrum was determined using UV-Vis spectroscopy in the wavelength range of 400nm to 700nm. The optical bandgap of the undoped and doped Cu 2 O was found to fall between 1.94 eV - 2.21 eV. Scanning Electron Microscopy (SEM) paired with energy dispersive x-ray (EDX) was used to observe the morphology and the presence of samarium in the synthesized Cu 2 O nanoparticles. The results show that upon adding Sm to the Cu 2 O, in a facile way, it could bring an important impact on optoelectronic devices such as photodiodes and solar cells.
