This study investigates the effects of TiO₂ concentration on the optical and dielectric properties of ZnO electrospun nanofiber thin films, with the aim of enhancing visible-light absorption and conversion efficiency. Electrospun solutions of titanium(iv) propoxide, zinc acetate dihydrate, poly(vinyl acetate), and N, N-dimethylformamide were deposited onto glass substrates and subsequently calcined. The resulting fibres had a mean width of approximately 250 nm. Structural and optical characterisation using SEM, EDS, RBS, XRD, and UV–Vis spectroscopy revealed no significant lattice interaction between Zn and Ti atoms, while optical analysis indicated a redshift in the absorption edge and narrowing of the bandgap from 2.89 eV (5% Ti) to 2.39 eV (25% Ti). Urbach tail analysis demonstrated reduced disorder with higher Ti content. The dielectric and optical conductivity parameters increased with photon energy, particularly around the bandgap region. This work highlights a facile and reproducible electrospinning route for tailoring ZnO–TiO₂ nanofibres towards efficient visible-light photocatalysis and other optoelectronic applications.
