Zinc telluride (ZnTe) quantum dots (QDs) were synthesized by a unique supersaturation-controlled aqueous route. For a given pH, increasing the degree of initial supersaturation led to a decrease in the average diameter (davg) of the QDs and increased

Femtosecond-Laser-Induced Saturable Absorption and Optical Limiting of Hollow Silver Nanocubes: Implications for Optical Switching and Bioimaging

Autor: B. Bhushan, Swastik Ballav, Prasanta Kumar Datta, Sayantan Bhattacharya, Amiya Priyam, Bhavesh Kumar Dadhich

Publikováno v: ACS Applied Nano Materials. 3:11620-11629

The effects of shape, size, and surface plasmon resonance (SPR) peak position (λSPR) on nonlinear absorption (NLA) were investigated at 808 nm, using a femtosecond laser. We found that NLA behavior...

Hollow Silver Nanostructures: The Role of Capping Agents in Tailoring the Shape, Structure, and Plasmonic Properties

Autor: Bhavesh Kumar Dadhich, Amiya Priyam, B. Bhushan

Publikováno v: Microscopy and Microanalysis. 25:1431-1436

The shape- and structure-directing ability of capping agents, namely, acetic acid (AA) and folic acid (FA), has been analyzed in the synthesis of hollow plasmonic nanostructures via the nanoscale Kirkendall effect. FA was found to possess both shape-

Folate-Directed Shape-Transformative Synthesis of Hollow Silver Nanocubes: Plasmon Tunability, Growth Kinetics, and Catalytic Applications

Autor: Amiya Priyam, Bhavesh Kumar Dadhich, Abhijit Saha, B. Bhushan

Publikováno v: ACS Applied Nano Materials. 1:4294-4305

A unique role of folate as a shape- and structure-directing agent has been found in nanosynthesis. Folate-capped Ag2O nanospheres transformed into hollow silver nanocubes (HAgNCs) having spherical void spaces during reduction with hydrazine hydrate (

Shape and size dependent nonlinear refraction and absorption in citrate-stabilized, near-IR plasmonic silver nanopyramids

Autor: Ravi Kant Choubey, B. Bhushan, Bhavesh Kumar Dadhich, Amiya Priyam, Indrajit Kumar

Publikováno v: Photochemical & Photobiological Sciences. 16:1556-1562

Using a combination of a mild stabilizer and a mild reductant, sodium citrate and hydrazine hydrate, anisotropic silver nanocrystals (NCs) were synthesized with tunable plasmon peaks at 550 nm, 700 nm, 800 nm, 900 nm and 1010 nm (the samples are name

Seed geometry and hydrogen bonding dependent plasmonic tuning of silver nanocrystals in a citrate–hydrazine matrix and SERS spectroscopic detection of chromium

Autor: Abhishek Swarnkar, Pradip Paik, Satarupa Pattanayak, Amiya Priyam

Publikováno v: RSC Adv.. 7:45911-45919

By employing a ‘mild stabilizer–mild reductant’ system, a seed-mediated synthesis of tunable anisotropic and plasmonic silver nanocrystals (NCs) has been developed. Differently shaped seed NCs were synthesized using citrate and hydrazine hydrat
