Improved photoluminescence quantum yield and stability of CdSe-TOP, CdSe-ODA-TOPO, CdSe/CdS and CdSe/EP nanocomposites

Materials Research Express, 2016
Size-controllable monodisperse CdSe nanocrystals with different organic capping were prepared based on the hot-injection method. The effective separation of nucleation and growth was achieved by rapidly mixing two highly reactive precursors. As a contrast, we prepared CdSe/CdS nanocrystals (NCs) successfully based on the selective ion layer adsorption ...

Synthesis of CdS and CdSe nanoparticles by thermolysis of diethyldithio- or diethyldiseleno-carbamates of cadmium [PDF]

, 1996
Cadmium sulfide and cadmium selenide nanoparticles have been synthesised by a novel route involving the thermal decomposition of the bisdiethyldithio- or bisdiethyldiseleno-carbamates of cadmium in refluxing 4-ethylpyridine solutions. The nanodispersed

Vacancy-Induced Electron Redistribution Boosts NO2 Sensing in CdSe Nanoplatelets via Defect-Mediated Charge Transfer

Environmental Chemistry and Safety
Defect engineering is crucial for enhancing gas sensors, however, the mechanism by which vacancies amplify sensing signals remains unclear. This study synthesizes hexagonal CdSe nanoplatelets with tunable vacancy density through a NaOH-regulated ...

Stereoelectronic effects on the binding of neutral Lewis bases to CdSe nanocrystals [PDF]

, 2018
Using P-31 nuclear magnetic resonance (NMR) spectroscopy, we monitor the competition between tri-nbutylphosphine (Bu3P) and various amine and phosphine ligands for the surface of chloride terminated CdSe nanocrystals.

Effect of ligand exchange on photocurrent enhancement in cadmium selenide (CdSe) quantum dot water splitting cells

Results in Physics, 2018
We report photocurrent enhancement through ligand exchange in cadmium selenide (CdSe) photoelectrochemical (PEC) cells. CdSe quantum dot (QD) layers were used as a light absorption layer in combination with titanium dioxide (TiO2) layers.

Study of Photoconductivity of Thin Films of Cadmium and Selenium Obtained by Chemical Deposition

East European Journal of Physics
In this work, the photoconductivity (PC) spectrum of thin CdSe films was studied. In the course of studies on glass substrates, thin films of cadmium and selenium with a thickness of h = 200 nm and h = 400 nm were selected.

Model-independent determination of the carrier multiplication time constant in CdSe nanocrystals [PDF]

, 2009
The experimental determination of the carrier multiplication (CM) time constant is complicated by the fact that this process occurs within the initial few hundreds of femtoseconds after excitation and, in transient-absorption experiments, cannot be ...
