Enhancement in photoluminescence emission in the UV-visible region from chemically synthesized silver doped ZnS nanoparticles

Kumbhakar P., Mitra A.K., Sarkar R., NIT Durgapur India, IN

Nanoparticles of ZnS:Ag doped with Ag+ (0.5%) and capped with polyvinyl pyrolidone (PVP) have been synthesized by chemical co-precipitation method. The measured particle size is ~2.5 nm which has been obtained from the analyses of [...]

Violet-Blue Emission From TiO2/SWCNT Hybrid Structure Synthesized by a Simple Chemical Route

Kumbhakar P., Mitra A.K., Paul R., NIT Durgapur India, IN

Using a lucid wet chemical process under room temperature, titania nanocrystallites of average size 5 nm have been adhered to the surfaces of SWCNT bundles. The hybrid structure has been characterized by high resolution transmission [...]

Effect of Position and Orientation of Stone-Wales Defects on the Fracture Behavior of a Zigzag Single-Walled Carbon Nanotube

Mitra A.K., Talukdar K., NIT Durgapur India, IN

A (10, 0) SWCNT of length 42.59 Å and aspect ratio 10.9 is studied by Molecular Dynamics (MD) simulation both in perfect condition and also with one, two, three or four SW defects introduced into [...]
