摘要：

Cubic BaTiO3 (C-BT) and tetragonal BaTiO3 (T1-BT) nanoparticles were prepared by a solvothermal method with controlling the Ba/Ti precursor ratio. Triethanolamine was additionally employed in the synthesis to obtain ferroelectric BaTiO3 with improved particle size distribution and tetragonality (T2-BT). The prepared nanoparticles were thoroughly characterized by scanning electron microscopy, transmission electron microscopy, Brunauer-Emmett-Teller analysis, X-ray diffraction, X-ray photoelectron spectroscopy, ultraviolet-visible spectroscopy, photoluminescence, and second-harmonic generation. Importantly, the BaTiO3 nanoparticles were introduced into the scattering layer of dye-sensitized solar cells and T2-BT showed better power conversion efficiency than C-BT and T1-BT.
