In this study, SrTiO₃ perovskite nanoparticles were synthesized using the sol–gel method. Strontium nitrate (Sr(NO₃)₂) and titanium isopropoxide were employed as precursors in a 1:1 molar ratio, while dimethyl sulfoxide (DMSO) was used as the solvent. The samples were prepared at concentrations of 0.1 M and 0.5 M. After the formation of the gel phase, the obtained materials were subjected to stepwise thermal treatment, including initial drying at 300 °C followed by calcination in the temperature range of 750–800 °C. The structural and optical properties of the synthesized materials were investigated using Fourier-transform infrared (FTIR) and UV–Vis spectroscopy techniques. FTIR analysis confirmed the formation of characteristic Ti–O and Sr–O bonds associated with the perovskite structure. The UV–Vis spectra revealed strong absorption in the ultraviolet region and demonstrated the semiconducting nature of the synthesized samples. The results indicate that the sol–gel method enables the preparation of highly homogeneous and thermally stable SrTiO₃ nanoparticles. The obtained materials show significant potential for applications in photocatalysis, optoelectronics, and functional ceramics.
