This analysis demonstrates how lithium doping enhances optical properties and photocatalytic efficiency in TiO2 thin films, suggesting improved dye degradation rates.
In this study, we investigate the impact of lithium (Li+) doping on the structural, morphological, optical, and photocatalytic properties of TiO2 thin films. Li+-doped TiO2 films were fabricated on glass substrates using the sol–gel spin-coating technique and subsequently annealed at 550°C for 2 h. X-ray diffraction analysis confirmed that all films crystallize exclusively in the anatase phase. The crystallite size was found to decrease from 19 to 13 nm with increasing Li+ doping. The surface morphology, examined through scanning electron microscopy and atomic force microscopy, revealed noticeable changes influenced by the Li+ content. With higher Li+ concentrations, optical transmittance (T [%]) increased, while the optical band gap (Eg [eV]) decreased. Additionally, lithium doping enhanced the photocatalytic efficiency of TiO2 films in degrading methylene blue.
