| 中文摘要 | Perovskite oxide La(0.825)Sro(0.175)MnO(3) (LSMO) nanowires are synthesized using the anodized alumina oxide template technique and the characterization of the microstructure, magnetic and photol uminescence properties is performed. The as-prepared LSMO nanowires 50 nm in diameter and tens of microns in length exhibit polycrystalline perovskite structure. The magnetic measurement reveals the competition between anti ferromagnetic ordering and spin glass state as ground state in the nanowires, which is different from the magnetic behaviours of bulk ceramic and single crystals. The photoluminescence (PL) spectroscopy demonstrates strong and broadband emissions with two luminescent peaks at 400 and 420 nm, respectively, which are believed to originate from the self-trapped excitons, oxygen vacancies and surface states, respectively. |
