Park emission and quantum yield characteristics of each structure at different particle sizes are listed in the following table: Typical spectra for CdSe core quantum dotsįigure 3. The typical absorption and emission spectra for CdSe core quantum dots are illustrated in Figure 2, and Figure 3 shows a TEM-image of single quantum dots.įigure 2. High batch-to-batch reproducibility (TEM available for each lot).Scalability (manufactured through continuous flow).Homogeneous dispersions in different non-polar solvents possible.Flexibility for ink or composite preparation.The following are the key characteristics of StremDots™ quantum dots: Key Characteristics of StremDots™ Quantum Dots The thiol groups encourage the adsorption of these macromolecular constructs on the ZnS shell of the. The characteristics and corresponding ligand capping agent for each structure are listed in the following table: Structure We synthesized macromolecular ligands for CdSe-ZnS core-shell quantum dots incorporating multiple thiol groups, poly (ethylene glycol) chains, and either carboxylic acids or primary amines along a common poly (methacrylate) backbone. The second shell of ZnS has a thickness range of 1-2nm and provides additional stability. ![]() The CdS or ZnSe shell is below 1nm and provides stability to the core. The CdSe core has a highly uniform structure with a narrow particle size distribution of ☑0%. In this work, the effects of electrochemical control on photoluminescence (PL) spectra in core/shell CdSe/ZnS QD films are studied. Electrochemical modulation is a good way to understand the electrical and optical properties of QDs. Moreover, the superb photostability can be combined with a low number of defects by using CSQDs with a gradient composition change from the core to the shell. Semiconductor quantum dots (QDs) are widely used in light-emitting diodes and solar cells. Strem Chemicals provides fluorescent quantum dots (Figure 1) in the following structures: Coreshell (CS) quantum dots (QDs) are promising light absorbers for solar cell applications mainly because of their enhanced photostability compared with bare QDs.
