摘要

全面了解利用水热法合成分层结构纯钒氧化物和掺杂钒氧化物的新方法。在光致发光（PL）信号中，脱ocalization 电子转变在 361.31 nm 处出现强吸收带。在双掺杂样品中，这种吸收增加了可见光区（蓝绿色）的光吸收。纯材料和掺杂材料的循环伏安法（CV）结果显示，纯物质的阳极和阴极峰扩大。量子化学计算分析给出了突出的分子几何形状。分子静电位（MEP）确认分析表明，掺杂阳离子的物质具有最小能量。对所选样品的生物活性进行了表征。

Low Dimensional vanadium pentoxide nanomaterial: Experimental and theoretical characterization on enhancing LED performance

Comprehensive understanding about the novel approach of sysnthesis of hierarchically structured pure and doped vanadium oxides using hydrothermal route. Delocalization electron transition appears the strong absorption band at 361.31 nm in the Photoluminescence (PL) signals. In dual doped samples this absorption increases the optical absorption in visible region (blue-green). Cyclic Voltammetry (CV) results obtained for pure and doped materials shows the expanded anodic and cathodic peaks of pure substance. The quantum chemical calculations analysis gives prominent molecular geometry. The confirmation analysis, Molecular Electrostatic Potential (MEP) reveals that cation doped substance has minimum energy. The biological activities of selected samples are characterized.

期刊介绍： Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage. Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
