Hydrothermal Synthesis and Photoluminescence of Pre-Perovskite Lead Titanate Nanofibers

摘要

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.
