Lead Telluride Quantum Dots: The modern fabrication techniques of electronic, optoelectronic, and sensoric devices has renewed the interest in self-organization and self assembly of nano-structures like quantum dots (QDs) or quantum wires embedded in solid matrices. A variety of structures and materials is found to be promising for future applications in optoelectronics or nanoelectronics. In these cases the confinement of the electron or the hole wave functions are of particular interest, since they exhibit properties similar to those of single atoms or molecules.
Lead Telluride Quantum Dots: Nanoshel Lead telluride quantum dot-based solar cells, which produce extractable, charge carrier pairs with an external quantum efficiency above 120%, and our team estimate an internal quantum efficiency exceeding 150%. The small size of the embedded QD leads to spatially confined (within the PbTe QD) electron and hole wave functions. As a result of this restriction the electronic band gap is typically increased by Econf.
Lead Telluride Quantum Dots: Lead Telluride (PbTe) is a black-blue crystalline solid with a rock salt- halite crystal structure. In a rock salt structure, the atoms are arranged in a face center cubic (FCC) unit cell with a Fm3m space group. The unit cell expresses the structure of the solid. In a crystal, the unit cell is repeated numerous times to fully assemble at a larger scale. It has been reported that nanocrystals with rock salt unit cells have high surface energies.
Lead Telluride Quantum Dots: Many synthetic routes have been established in synthesizing QDs. Lead telluride QD’s can be studied in gas phase, colloidal suspension or implanted on sold surfaces. Physical methods use electrochemical methodologies. Chemical composites are lithographically formulated and deposited onto a substrate. Such techniques include Molecular Beam Epitaxy (MBE) and doping on glass matrices.
Lead Telluride Quantum Dots Combining attractive properties of high brightness, robust photostability and excellent biocompatibility, this new NIR-II emitting Qdot is highly promising in accurate disease screening and diagnostic applications.
