Preparation of CeO2 nanoparticles by laser ablation in liquid method and its UV-absorption properties

The absorption of the ultraviolet-A (UVA), which causes imperceptible harm to human skin, was studied in CeO 2 nanoparticles. The CeO 2 nanoparticles with a high UVA ultraviolet absorption property were generated using laser ablation in the liquid approach without the use of any additives or surfact...

Description
Summary:The absorption of the ultraviolet-A (UVA), which causes imperceptible harm to human skin, was studied in CeO 2 nanoparticles. The CeO 2 nanoparticles with a high UVA ultraviolet absorption property were generated using laser ablation in the liquid approach without the use of any additives or surfactants. The properties of CeO 2 nanoparticles were observed by controlling the concentration of nanoparticles, laser beam’s energy intensity, and irradiation time. X-Ray Diffraction, Scanning Electron Microscopy (SEM), Dynamic Light Scattering (DLS), and Ultraviolet–Visible spectra were used to determine the morphology and optical properties. In this study, spherical CeO 2 nanoparticles were dispersed in a suspension liquid with the sizes ranging from 5 to 50 nm using SEM and DLS observations. In addition, the absorbance in the wavelength range in UVA of the CeO 2 nanoparticles-dispersed solution with the 200–400 nm waveband was first studied to show the potential of CeO 2 nanoparticles as a UV-filtering material. In addition, the impact of laser irradiation on the spherical CeO 2 nanoparticles’ formation and their aggregation phenomena were discussed in this research and an approach for preparing CeO 2 nanoparticles with spherical morphology was offered.
