“…However, the increase of intensity of background with wavenumber in Raman spectrum in Figure 10 indicates the photo-luminescence (PL) of the BTO-Au sample at high Au loading. Observation of PL was also reported for BTO-Au nanocomposite prepared by sol-gel method [15]. In our conditions the PL of pure BTO NPs is wide and is red-shifted for more than 100 nm compared to BTO synthesized by chemical synthesis.…”

“…Peak of PL observed in our work at 540 nm is attributed to the plasmonic luminescence of Au NPs supported on BTO NPs [ 30 ]. This peak was not reported for BTO-Au nanocomposite synthesized by sol-gel procedure [ 15 ].…”

“…BaTiO 3 (BTO) has attracted much attention with respect to its high dielectric constant and refractive index [20,21], chemical stability, environmental benignity, and excellent optical property [22]. However, the photocatalytic activity of BTO is also suffered by its wide E g (~3.18 eV) [23], which has response only to UV light.…”

“…And the wide band gap limits its photocatalytic efficiency . In order to improve the photocatalytic activity, various strategies have been proposed such as bandgap engineering, morphology tuning, metal loading and heterojunction modification to expand the scope of use solar energy and increase the charge carrier separation efficiency.…”
