Cuprous oxide quantum particles as small as 2 nm (comparable to the Bohr exciton radius) were synthesized using an electrochemical route. Quantum confinement effects are evident from a blueshift in the optical absorption. The optical absorption spect

Size effects in cupric oxide nanocrystals, synthesized using a novel electrochemical route, having average diameters of about 4 and 6 nm, are probed by x-ray photoelectron spectroscopy. Cu---O bond ionicity was found to increase with reduction in nan

We report a novel method for the synthesis of stable, OH free zinc oxide quantum dots, using an electrochemical route. The optical properties of these quantum dots were studied at room temperature, by taking the optical absorption and luminescence sp

The luminescent properties of undoped ZnO quantum dots encapsulated in various stabilizing agents have been investigated at room temperature. Stoichiometric as well as non-stochiometric ZnO quantum dots have been prepared by different routes. These s

We report preparation and characterisation of stable and size fixed Cu doped ZnO Quantum Dots. The unique luminescent properties have been observed at room temperature. The incorporation of Cu in the ZnO matrix is responsible for quenching the green

Two-dimensional nanoparticle self-assemblies provide a means of tuning the optical properties by manipulation of the fabrication parameters, thereby controlling the light-matter interaction. We report fabrication of self-assembled monolayers of collo
