Study the Effect of Sintering Temperature on the Structural and Optical Properties of Y₂O₃ Nanoparticles Synthesized by Sol Gel Method

Abstract:

The different characteristics of nanoparticles (NPs) are mostly determined by the sintering process. The goal of the current study is to examine how the sintering temperature affects the optical and structural characteristics of Y₂O₃ NPs made using the sol-gel method. For a competitive study, the synthesized Y₂O₃ NPs were sintered for three hours at 300, 600, and 900°C. The generated Y₂O₃ NPs were sintered for three hours at 300, 600, and 900°C in this work. Samples of Y₂O₃ NPs are designated Y1, Y2, Y3, and Y4, in that order. The cubic structure of Y₂O₃ NPs is confirmed by XRD examination, which also corresponds to JCPDS card No. 083-0927. For Y1, Y2, Y3, and Y4, the crystallite sizes were determined to be 12.58, 12.24, 12.05, and 09.16 nm, respectively. The optical characteristics, such as energy bandgap fluctuations and light absorption, were investigated using UV-Vis spectroscopy. Usually, the absorbance peak shows up between 230 and 250 nm. For Y1, Y2, Y3, and Y4, the energy band gap was determined to be 4.51, 4.40, 4.31, and 4.19 eV, respectively. The vibrational modes of the Y₂O₃ NPs are examined, which provides further evidence of phase purity and structural stability. Increased band gap, better crystallinity, and a lower percentage of oxygen atoms all help the material's mechanical and chemical durability as well as its shine, which makes it more suitable for dental ceramic applications.
