Abstract
Aluminum doped zinc oxide nanoparticles (AZO) with different doping concentrations were prepared by Nd-YAG laser ablation of target in deionized water. The characterization of these nanoparticles was performed using Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and photoluminance spectroscopy (PL). FTIR spectra confirmed the formation of vibrational bonds for ZnO NPs and AZO NPs. SEM images illustrated that the size and shape of the NPs changed with changing the number of laser pulses. Photoluminescence peaks exhibited two emission peaks, one at the UV region and the second in the visible region, which were modified as the number of laser pulses and doping concentration were changed.
Highlights
Pulse laser ablation in liquid (PLAL) is a media of solid target approach that is considered as an efficient technique to prepare materials in nanoscale size, due to many advantages, such as being simple, clean, and of high purity production [1]
Zinc oxide (ZnO) is one of the promising nanomaterials prepared in different methods, owing to the wide range of applications in optoelectronic devices, energy storage, and biomedical sciences [18,19,20,21,22]
Figure-1 shows the Fourier transform infrared (FTIR) spectra of zinc oxide (ZnO) nanoparticles prepared by laser ablation in liquid at different numbers of pulses (25, 50, 75, 100, and 125)
