DNA Origami Directed Au Nanostar Dimers for Single-Molecule Surface-Enhanced Raman Scattering
(American Chemical Society, 2017)
We demonstrate the synthesis of Au nanostar dimers with tunable interparticle gap and controlled stoichiometry assembled on DNA origami. Au nanostars with uniform and sharp tips were immobilized on rectangular DNA origami ...
Core size matters! High Raman enhancing core tunable Au/Ag bimetallic core-shell nanoparticles
(Springer Verlag, 2017)
Bimetallic core-shell nanostructures have been attracted tremendous attention due to their ability to form novel materials with unique chemical, optical, and physical properties. Here, we have studied the influence of core ...
Nonlinear optical switching and optical limiting in colloidal CdSe quantum dots investigated by nanosecond Z-scan measurement
(Elsevier Ltd, 2016)
The semiconductor nanocrystals are found to be promising class of third order nonlinear optical materials because of quantum confinement effects. Here, we highlight the nonlinear optical switching and optical limiting of ...
One-Pot Synthesis of Au Embedded ZnO Nanorods Composite Heterostructures with Excellent Photocatalytic Properties
(Wiley-Blackwell, 2018)
Here, we have designed a noble composite nanostructure by embedding gold (Au) nanoparticles into zinc oxide (ZnO) nanorods surface in one pot synthesis as a photocatalyst. The formation the composite nanostructure was ...
Structural and electronic investigation of metal-semiconductor hybrid tetrapod hetero-structures
(Springer Verlag, 2017)
This article highlights the new electronic properties of tetrapod hetero-structures with metal Au core and semiconductor CdSe arms, which is one of the new classes of hybrid metal-semiconductor nanostructures. From the ...
Novel Green Approach for Fabrication of Ag2CrO4/TiO2/Au/r-GO Hybrid Biofilm for Visible Light-Driven Photocatalytic Performance
(American Chemical Society, 2020)
Development of cutting edge materials using a benevolent ecologically cordial methodology is an ideal approach for heterogeneous visible light photocatalysis. A new biogenic photocatalyst was developed by coupling titanium ...
Fabrication of mesoporous titanium dioxide using azadirachta indica leaves extract towards visible-light-driven photocatalytic dye degradation
(Elsevier, 2020)
An environmental benign, straightforward and financially savvy technique has been developed to fabricate mesoporous titanium dioxide (TiO2) nanostructure utilizing Azadirachta indica leaves extract. The aqueous extract of ...
