Hydrothermal Routes for the Synthesis of CdSe Core Quantum Dots

چکیده
Semiconductor nanocrystals, also called quantum dots (QDs), are fluorescent inorganic particles with typical diameters ranging from 1 to 10 nm. Due to their quantum confinement, QDs show unique and fascinating optical properties that are advantageous in the fields of photovoltaic devices, light-emitting diodes, biological imaging, biodiagnostics,... (Costa-Fernandez et al., 2006; Lim et al. 2007; Medintz et al., 2005; Robel et al., 2006). CdSe QDs are probably the most extensively investigated colloidal II-VI semiconductor nanoparticles because (i) their band gap can be tuned across the visible spectrum by variation of their diameters, and (ii) of the advances made in their preparation.

Investigation of the Third-Order Nonlinear Optical Susceptibilities and Nonlinear Refractive Index In Pbs/Cdse/Cds Spherical Quantum Dot
In this study the third order nonlinear susceptibilities are theoreticallycalculated for an electron confined in an isolated PbS/ CdSe/ CdS spherical core-shellshellquantum dots. Our calculation is associated with intersubband transitions in theconduction band. We used the effective mass approximation in this study which is asimple and straightforward study of the third-order optical nonlineari...
متن کاملSingle Enzyme Direct Biomineralization of CdSe and CdSe-CdS Core-Shell Quantum Dots.
Biomineralization is the process by which biological systems synthesize inorganic materials. Herein, we demonstrate an engineered cystathionine γ-lyase enzyme, smCSE that is active for the direct aqueous phase biomineralization of CdSe and CdSe-CdS core-shell nanocrystals. The nanocrystals are formed in an otherwise unreactive buffered solution of Cd acetate and selenocystine through enzymatic ...
متن کاملP-156: A Study about Toxicity of CdSe Quantum Dots on Male Sexual System of Mice and Controlling This Toxicity by ZnS Coverage in Immature Mice
Background: Quantum dots are commonly composed of cadmium contained semiconductors. Cadmium is potentially hazardous but toxicity of such quantum dots is not yet systematically investigated. On the other hand, in vitro studies have shown almost complete control of CdSe induced cytotoxicity by ZnS coverage. Toxicity of CdSe quantum dots and controlling this toxicity by ZnS coverage in immature m...
متن کاملA comparative study about toxicity of CdSe quantum dots on reproductive system development of mice and controlling this toxicity by ZnS coverage
Objective(s): Medicinal benefits of quantum dots have been proved in recent years but there is little known about their toxicity especially in vivo toxicity. In order to use quantum dots in medical applications, studies ontheir in vivo toxicity is important. Materials and Methods:CdSe:ZnS quantum dots were injected in 10, 20, and 40 mg/kg doses to male mice10 days later, mice were sacrificed ...
متن کاملIn vivo Effects of CdSe Injection on Embryonic Development of Reproductive System
The use of quantum dots (QDots) as bright and photostable probes for long-term fluorescence imaging is gaining more interest. Thus far, (pre)clinical use of QDots remains limited, which is primarily caused by the potential toxicity of QDots. Most QDots consist of Cd2+ ions, which are known to cause high levels of toxicity. Therefore, the cytotoxic effects of CdSe quantum dots on embryonic devel...
