Nanoparticles research is at the forefront because of its enormous technological potentialities. Throughthe hydrothermal method, yttrium oxide nanoparticles having multiform morphologies are successfullysynthesized. The morphology, structure, photoluminescence properties, and functional groups of thesenanoparticles were studied through scanning electron microscopy (SEM), powder X-ray diffraction(PXRD), Fourier-transform infrared spectrometry (FTIR), photoluminescence spectroscopy (PL) andUV-Visible (UV-Vis) analyses. The XRD results showed that the neat samples have cubic Y2O3 structure.SEM micrographs revealed that the samples comprised aggregated nanoparticles having differentsizes and shapes. The UV-Vis spectra indicated that the absorption peak position shifted towards thelower wavelength with a decrease in the particle size because of the changing surface structures andmorphologies. Photoluminescence spectra showed a PL emission with a broad peak at approximately564 nm, when the sample was excited by 280 nm wavelength. FTIR and EDAX spectra confirmed thepresence of metal oxides. Yttrium oxide nanoparticles can counteract the influence of oxidativemetabolites and present an antioxidant activity with the IC50 of 86.84 μg/mL. These properties indicatedthat these nanoparticles have a potential in biomedical and optoelectronic applications.
