Erbium-doped barium titanate (BaTiO 3 :Er) xerogel film with a thickness of about 500 nm was formed on the porous strontium titanate ([Formula: see text] xerogel film on Si substrate after annealing at 800[Formula: see text]C or 900[Formula: see text]C. The elaborated structures show room temperature upconversion luminescence under 980 nm excitation with the photoluminescence (PL) bands at 523, 546, 658, 800 and 830 nm corresponding to 2 [Formula: see text] 4 [Formula: see text], 4 [Formula: see text][Formula: see text], 4 [Formula: see text][Formula: see text] and 4 [Formula: see text] 4 [Formula: see text] transitions of trivalent erbium. Raman and X-ray diffraction (XRD) analysis of BaTiO 3 :Er\porous SrTiO 3 \Si structure showed the presence of perovskite phases. Its excellent up-conversion optical performance will greatly broaden its applications in perovskite solar cells and high-end anti-counterfeiting technologies.
