Effect of Increasing Ablation Energy on the Physical Properties of CuO and Al2O3 Nanoparticles
Keywords:
Laser, AblationAbstract
In this study, copper (Cu) and aluminium (Al) nanoparticles (NPs) were
prepared to study their physical properties in a simple, easy and
environmentally friendly way using a switched Nd:YAG laser by
bombarding the target placed in a liquid-filled beaker at a rate of 600 pulses
per second, an ablation energy of 200 and 400 mJ and a frequency of 2 Hz.
The XRD results indicate that cubic symmetry was obtained for copper and
also for aluminium. The average nanoparticle size determined by TEM was
(20 nm) for copper and the average size of aluminium diameters was (22
nm). As for the optical properties, at 200, and 400 mJ the surface plasmon
resonance (SPR) peak for copper was at (295, and 655 nm) while aluminium
was at (288, and 289 nm) respectively, and the energy gap for copper was
(3.17, and 3.2 eV) and aluminium was (4.6, and 4.7 eV) respectively. These
materials are very useful for applications in photocatalysis and sensors.
