Inclined Substrate Deposition of Nanostructured TiO2 Thin Films for DSSC Applic...
Meng, Lijian; Yang, TaoNanostructured TiO2 films were deposited onto Indium Tin Oxide (ITO) and glass substrates by dc reactive magnetron sputtering at different substrate inclination angles. The structural and optical properties of the deposited films were studied by X-ray diffraction, scanning electron microscopy and UV-Vis spectrophotometer, respectively. Dye-sensitized solar cells (DSSC) were assembled using these TiO2 films as p...

Nitrogen-doped carbon encapsulated zinc vanadate polyhedron engineered from a m...
Fang, Yixing; Chen, Yilan; Zeng, Lingxing; Yang, Tao; Xu, Qinxin; Wang, Yiyi; Zeng, Shihan; Qian, Qingrong; Wei, Mingdeng; Chen, QinghuaIn this work, we fabricated vanadium/zinc metal-organic frameworks (V/Zn-MOFs) derived from self-assembled metal organic frameworks, to further disperse ultrasmall Zn2VO4 nanoparticles and encapsulate them in a nitrogen-doped nanocarbon network (ZVO/NC) under in situ pyrolysis. When employed as an anode for lithium-ion batteries, ZVO/NC delivers a high reversible capacity (807 mAh g-1 at 0.5 A g-1) and excellen...
An investigation of annealing methods for benzodithiophene terthiophene rhodani...
Guangwen, Li; Yang, Tao; Cheng, Hao; Zhang, Youdi; Wang, Jian; Liu, YuzhouMainstream organic solar cells (OSCs) suffer a great variation of photovoltaic performance among different batches of polymers, which brings an opportunity for all-small-molecule OSCs to take leading position of industrialization. In recent years, benzodithiophene terthiophene rhodamine (BTR), as small molecule donor, has played an important role in this field. Here we investigated two typical BTR based all-sma...
Combustion synthesis of Ce2LuO5.5:Eu phosphor nanopowders: structure, surface a...
Shi, Shikao; Wei, Dan; Li, Keyan; Wang, Shuping; Fu, Lianshe; Yang, Tao; Meng, LijianThe spherical shape, uniform size and small degree of agglomeration of the particles play crucial roles in promoting the practical applications of the phosphor powders. In this paper, the novel Eu3+ -doped cerium lutetium Ce2LuO5.5 composite nanopowders with a cubic fluorite structure were prepared via a typical solution combustion route, and their internal structure, surface morphology as well as luminescence ...

Hydrothermal synthesis and optimization of boron doped LiZr2(PO4)3 Li-ion solid...
Yang, Tao; Almeida, Carlosde; Han, Dezhi; Meng, Lijian; Deng, Jiguang; Silva, E.L. da; Santos, M.C.; Shi, ShikaoBoron doped LiZr2(PO4)3 electrolyte was successfully synthesized via facile hydrothermal synthesis. Our results show that boron doping mainly happens on the Zr-site of Li1+xZr2-xBx(PO4)3 not the P-site of Li1+6xZr2(P1-xBxO4)3. Rietveld refinement of the unit-cell parameters was performed, and it was verified by consideration of Vegard’s law that it is possible to obtain phase purity up to x= 0.05 in Li1+xZr2-xB...
Highly branched Pt Cu nanodandelion with high activity for oxygen reduction rea...
Yang, Tao; Pukazhselvan, D.; da Silva, E.L.; Santos, Mario C.; Meng, Lijian; Ramasamy, Devaraj; Jothi, Sathiskumar; Graça, Vanessa; Shi, ShikaoA facile hydrothermal route has been developed to synthesize the highly branched Pt58Cu42 nanoparticles via mixing the H2PtCl6 and CuCl2 with octadecylamine. The Pt58Cu42 after post treatment forms a dandelion flower 3-D structure. A combination of both the branched shape and PtCu composition effects in the Pt58Cu42-nanoparticles shows superior electrocatalytic activity and durability to commercial Pt black for...
The effect of hydroxyl on dye-sensitized solar cells assembled with TiO2 nanorods
Meng, Lijian; Yang, Tao; Yun, Sining; Li, CanTiO2 nanorods have been prepared on ITO substrates by dc reactive magnetron sputtering technique. The hydroxyl groups have been introduced on the nanorods surface. The structure and the optical properties of these nanorods have been studied. The dye-sensitized solar cells (DSSCs) have been assembled using these TiO2 nanorods as photoelectrode. And the effect of the hydroxyl groups on the properties of the photo...

Meng, Lijian; Xu, Wei; Zhang, Qingyu; Yang, Tao; Shi, ShikaoBismuth oxide films were deposited onto quartz substrates by radio frequency reactive magnetron sputtering using a bismuth metal target. The substrate temperature was varied from room temperature to 500 oC. The state of Bi ions in the deposited films was characterized by XPS and the results showed that Bi ions existed as Bi3+ ions. The film structure was characterized by XRD and Raman scattering. The film depos...
