CdS quantum dots for measurement of the size-dependent optical properties of thiol capping

Facile synthesis of CdS@TiO2 core–shell nanorods with controllable shell thickness and enhanced photocatalytic activity under visible light irradiation

“…The peak at around 1631 cm −1 is assigned to the deformation vibration for H-O-H bonds of physisorbed water[53][54][55][56]. The peak at around 1119 cm −1 can be attributed to the Cd-S bond[46,57], which appears only for the bare CdS and incompletely coated CdS@TiO 2 -1 sample. This peak disappears with the introduction ofTiO 2 shell.…”

Electrochemistry of chemiluminescent novel hybrid nanocomposites based on polyaniline and hydrolyzed pectin with CdS nanoparticles

“…In the IR spectrum of CdS@HPEc-g-PANi beside the appearance of the absorption bands of the PANi and HPEc at the corresponding regions, the peaks at $602 and $697 cm À1 can be corresponding to the CdS vibrations. 22 In CdS@HPEc-g-PANi nanocomposite, the absorption peak related to C]C stretching of benzenoid structure was shied to lower region from $1474 cm À1 to $1467 cm À1 compared to the HPEc-g-PANi. This shi may be due to chelating interactions between CdS and nitrogen atoms of benzenoid units on the surface of PANi in CdS@HPEc-g-PANi.…”

Spectacular oscillations in the dark and photocurrent in thiol-capped CdS quantum dots embedded in PMMA matrix

“…13 Interactions of nanoparticles with polymers are mediated by ligands attached to the nanoparticle, and the ligands markedly inuence particle behaviour and spatial distribution. [14][15][16] Our earlier study 10 showed bistable electrical conductivity, that is, conductance switching between two conducting states in the nanocomposites of PMMA with benzyl mercaptan (thiol)-capped CdS QDs.
