| Abstract: | Lead strontium titanate(Pb_xSr_(1-x))TiO_3(x=0.4,0.6) nanotubes were synthesized by sol-gel template method via spin coating.The structures and morphology of the as-prepared samples were characterized by X-ray diffractometry.scanning electron microscopy and transmission electron microscopy.X-ray photoelectron spectroscopy was used to determine the chemical composition of the sample and the valence state of elements.Raman spectroscopy of the as-prepared(Pb_xSr_(1-x))TiO_3(x=0.4,0.6) nanotubes at room tempera... |
