Hydrothermal Synthesis and Photoluminescence of Pre-Perovskite Lead Titanate Nanofibers

Abstract:

Pre-perovskite PbTiO₃ nanofibres were synthesized by hydrothermal method with four butyl titanate ((C₄H₉O)₄Ti) and lead nitrate (Pb (NO₃)) as the main precursors and Tetramethylammonium Hydroxide (TMAH) as mineralizer. X-ray diffraction (XRD), Raman, Scanning Electronic Microscopy (SEM), Transmission electron microscopy (TEM), high-resolution TEM (HRTEM), and the corresponding selected area electron diffraction (SEAD) were used to characterize the crystal structure and morphology of the obtained products. The results showed that the nanofibers are of a few to tens micrometer at length size, and 50~300 nm at diameter size. Based on the experimental results, the effect of Tetramethylammonium Hydroxide (TMAH) was simply discussed.
