Titanium dioxide (TiO2) nanoparticles possess outstanding physical, optical, and electrical characteristics, making them highly effective in the semiconductor industry. This research focuses on utilizing the sol–gel method to uncover the optical and electrical attributes of TiO2 nanopowder pallets. Through X-ray diffraction (XRD), the presence of both anatase and rutile phases of TiO2 powder is confirmed. The calculated values of crystallite size, FWHM, and diffraction angle are found to be 42 nm, 0.0058 nm, and 2θ = 270, respectively. Scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopy (EDS) reveals a porous surface and absence of impurities. The UV–Vis spectra indicate a direct band gap of 3.35 eV and PL spectra coupled with the CIE diagram, substantiate blue emission. The DC conductivity measurement demonstrates semiconducting behavior with a low resistivity of 6.22 × 10−3 Ω cm. These groundbreaking findings hold practical significance for advancing materials and devices, particularly in the realms of solar cells, sensors, and photocatalysis.Graphical Abstract:
