Their surface morphology, grain size measured after high temperature calci- nation and effect on the electrochemical performance of Li ion battery were discussed. TiO2 nanoflakes were charac- terizated by means of transmission electron microscopy(TEM), X-ray powder diffraction(XRD), N2 adsorp- tion-desorption isothermal assay, cyclic voltammetry(CV) and cycle performance test. The result of electrochemical performance test shows that the prepared TiO2 nanoflakes have high discharge specific capacity and good cycle per- formance. Discharge specific capacity for the first circle at the discharge rate of 0.1 C is 261.5 mA·h·g-1. After 90 cycles, the discharge capacity reduces to 172.2 mA·h·g-1.展开更多

Ga-Doped ZnO nanorod array photoanode devices were fabricatedvia hydrothermally growing nanorods on sol-gel spin-coating ZnO seed layer, and then the nanorod array was im-mersed into a thiophene solution to yield a thin polythiophene film by electrochemically polymerization. Afterwards,a thin layer of A1 was deposited on the surface of polythiophene to make an electrode for photovoltaic measurement.The ZnO nanorods with different Ga-doping contents were characterized by means of X-ray diffraction(XRD), scan-ning electron micrograph(SEM) and X-ray photoelectron spectroscopy(XPS). Photovoltaic J-V characterization wasperformed on the e-PT/ZnO bilayer and bulk heterojunction(BHJ) devices. Though the unsubstituted polythiophene isnot an ideal polymer material for solar cells with high power conversion efficiency, it is a sound model for the studyon the effect of dopant in hybrid materials. The results indicate that doping Ga can substantially improve the powerconversion efficiency of the ZnO-polythiophene solar cell.展开更多

The as-prepared crystals are mainly micrometer-scale plates, ranging from rhombus(SmCr0.5Fe0.5O3) to elongated hexagonal(SmCr0.5Mn0.5O3), and finally to well-edged rectangular(SmCr0.17Mn0.5Fe0.33O3) plates. Fe and Mn doped SmCrO3 crystals are indexed into Pbnm space group. The cell parameters of SmCr0.5Fe0.5O3 are slightly smaller than that of pristine SmCrO3. Binding energy analysis of Cr, Mn and Fe in SmCr0.17TMn0.5Fe0.33O3 sample indicates that they all possess +3 oxidation states. Temperature dependent magnetization of the as-prepared samples presents obviously stronger ferromagnetic interactions than the undoped counterparts. This work represents a remarkable development for hydrothelmal synthesis into fabricating perovskite oxide crystals with uniform distribution of doping ions.展开更多

The structural, morhpology and magnetic properties were characterized by means of powder X-ray diffraction, scanning electronic microscopy, as well as vibrating sample magnetometer and M6ssbauer spectroscopy, respectively. M6ssbaner spectroscopy demonstrates the coexistence of Sr2+, Ca2+ and Nd3+ at the C sites of the dodecahedrons for different substituted garnets. The crystal shape is dodecahedron, and the particle sizes are decreased with increasing the Ca and Sr doping concentrations. By recording the magnetic hysteresis loops and M-T curves at different temperatures, it can be seen that with the increasing x, the saturation magnetization values decrease while the coercive forces increase under the condition of high temperatures.展开更多
