IndirecttoDirect Bandgap Transition in AgDoped BaTiO₃ Thin Films: Combined Experimental and DFT Insights
Pristine BaTiO₃ (BTO) and Agdoped BaTiO₃ thin films (2–6 at. %) were synthesized on glass substrates at 300 °C using a costeffective spray pyrolysis technique. Ag incorporation initially reduced grain size up to 4 at. % and increased it at 6 at.%. XRD confirmed the tetragonal phase, with higher doping inducing lattice distortion and increased micro-strain. Optical analyses revealed an indirecttodirect bandgap transition accompanied by a reduction from 2.83 eV to 2.28 eV and a redshift in absorption due to Ag4d/O2p hybridization and oxygenvacancy states. Temperaturedependent resistivity indicated trapassisted smallpolaron hopping at low doping and partial mobility recovery at higher levels. DFT results supported Aginduced states near the valenceband maximum and a transition to a direct bandgap, highlighting potential for photovoltaic applications.
