A novel Cu and boron doped graphitic carbon nitride catalyst (Cu-CNB) was synthesized using cheap precursors and systematically characterized. The selective oxidation of toluene proceeded very smoothly over the catalyst at 70 °C using tert-butyl hydroperoxide (TBHP) as the oxidant to exclusively afford benzaldehyde. The catalyst can be used for at least five cycles without decrease in activity ...

In recent years, studies on the efficient spatial charge separation for broad solar light absorption and water remediation have been a major priority. Moreover, development of transition metal-doped nanocomposites this purpose is new endeavor in current research. Here, we constructed an Fe3+-doped CdO/ZnS nanocomposite with low doping level investigated effect transfer recombination behavior im...

The growth mechanisms of small cationic silicon clusters containing up to 11 Si atoms, exohedrally doped by V and Cu atoms, are described. We find that as dopants, V and Cu follow two different paths: while V prefers substitution of a silicon atom in a highly coordinated position of the cationic bare silicon clusters, Cu favors adsorption to the neutral or cationic bare clusters in a lower coor...

We report on a method to enhance the light-emission efficiency of printable thin films of a polymer doped with luminescent (CdSe)ZnS nanocrystals via metallic nanoparticles and nanoimprinted photonic crystals. We experimentally show a strong fluorescence enhancement of nanocrystals by coupling exciton-plasmon with the localized surface plasmon of metallic nanoparticles. The emitted light is eff...

In this paper, we report structural and optical properties of Mn doped ZnS nanoparticles, having average size 2.44–1.60 nm have been synthesized by co-precipitation method using Thioglycolic Acid as external capping agent. Zinc blende crystal structure ZnS:Mn nanoparticles has been confirmed by the X-ray diffraction studies. Absorption spectra have been obtained using UV-Vis spectrophotometer t...
