1D Morphology Stabilization and Enhanced Magnetic Properties of Co : ZnO Nanostructures on Codoping with Li: A Template-Free Synthesis

Onattu D. Jayakumar, +6 more
- 26 Aug 2009 - 
TL;DR: In this article, a morphological control and transformation of ZnO nanorods to spherical particles induced by Co substitution is reported. And the morphology completely reverts back to rod shape by Li incorporation.
Journal ArticleDOI

The effect of titanium on the lithium intercalation capacity of V2O5 thin films

M.B. Sahana, +6 more
- 30 Oct 2009 - 
TL;DR: In this article, the effect of 5% Ti incorporation on lithium intercalation capacity of V 2 O 5 thin films prepared by spin coating using metalorganic (MO) and inorganic sol-gel (SG) precursors on indium tin oxide coated glass substrates have been investigated.
Journal ArticleDOI

Whispering Gallery Mode Assisted Enhancement in the Power Conversion Efficiency of DSSC and QDSSC Devices Using TiO2 Microsphere Photoanodes

Tapan Kumar Das, +2 more
TL;DR: In this paper, a composite comprising a TiO2 mesoporous microsphere with smooth surface (SμS-TiO2) exhibiting whispering gallery modes (WGM) and a commercial TiO 2 nanoparticle (Degussa P25) with an optimum ratio (80:20 wt %) showed significant enhancement in photoconversion efficiency (PCE) of DSSC and QDSSC devices.
Journal ArticleDOI

Magnetic properties of hydrogenated Li and Co doped ZnO nanoparticles

O. D. Jayakumar, +4 more
- 15 Nov 2006 - 
TL;DR: In this paper, the effect of hydrogenation on the magnetic properties of Zn0.85Co0.05Li0.10O nanoparticles was investigated and it was found that the sample hydrided at room temperature (RT) showed weak ferromagnetism, while the sample hydrogenated at 400°C showed robust ferromagnetic properties.
Journal ArticleDOI

Defects in room-temperature ferromagnetic Cu-doped ZnO films probed by x-ray absorption spectroscopy.

Q Ma, +6 more
- 01 Aug 2012 - 
TL;DR: The results reveal unambiguously that atomic point defects exist in these RTFM thin films and provide strong support for defect-mediated ferromagnetism in Cu-doped ZnO thin films.
