Experts Review:

Dr. Ms. Kamiko Chang, Ph.D(University of Science and Technology Beijing, China)
CdSe Quantum Dot Band Gap have strong fluorescence in the visible region. Fluorescence is the emission of a photon from a molecule as an electron goes from an excited state to a ground state. The color of the emission depends on the energy difference between states. Cadmium is highly toxic because it disrupts zinc-binding proteins in the body. Because of this toxicity, a review of MSDS information for all reagents should be completed and summarized in your lab notebook before lab.

CdSe Quantum Dot Band Gap were prepared from the pyrolysis of dimethylcadmium and tri-n-octylphosphine selenide sTOPSed in a hot coordinating solvent of tri noctylphosphine oxide sTOPOd using the procedure described previously. In this method, the surface of the CdSe quantum dot was passivated with TOPO molecules to avoid surface oxidation and aggregation.

CdSe Quantum Dot Band Gap have discrete energy bands in which electrons can exist. When no electrons are excited, they will be in lowest possible energy band, however, due to the Pauli Exclusion Principle, each energy band can only accommodate a finite number of electrons. For this reason, it is the outermost two energy bands, the valence band and the conduction band, which have the greatest effect on the material’s electrical properties.

CdSe Quantum Dot Band Gap wells are structures characterized by a region of low potential of width d surrounded by essentially infinite potential, confining any and all particles within the well. By convention, the potential inside the well is set to zero in order to simplify solving the Schrödinger equation, and since the sides are infinite, it has no effect on the solution.

CdSe Quantum Dot Band Gap are put into layered structures to create lasers. At this point, electrical control is very important because an electric field applied to the structure can change certain physical properties of QDs in a desirable way and carriers can be injected into the structure to create light emission.
