Nanodots and Quantum Dots

About

A quantum dot is a single crystal of semiconducting material, measuring only a few nanometers in diameter. With enhanced electrical and optical properties, quantum dots are the cutting-edge of nanotechnology. Features and Applications When excited, these materials confine electrons and holes. The smaller the dot, the greater the confinement energy, leading to higher energy absorption and emission. This means more efficient photon management for your applications. Our selection of quantum dots guarantees high purity with properties including, chemical inertness, high tolerance, or low toxicity. Quantum dots find use in a wide range of applications. With good biocompatibility, they are ideal for drug delivery and bioimaging; or with excellent photoluminescent quantum yields, they have huge potentials in solar cells and LED displays.

Molecular engineering is simply the design and synthesis of molecules with specific properties and functions in mind. Certain chemical groups and atoms incorporated into molecules results in them having certain characteristics. Read more... What is molecular electronics? Molecular electronics or "moletronics" is to use molecules as building blocks to create electronic components. These molecular electronic components include transistors, diodes, capacitors, insulators, and wires. Read more... More on Quantum Dots The most studied quantum dots are metal chalcogenide dots. These are based on semiconductors such as cadmium selenide, indium phosphide or lead(II) sulfide. The bandgap of such quantum dots can be tuned throughout the entire visible spectrum simply by changing their size during chemical synthesis. For the highest photoluminescence quantum yields (PLQY), a shell structure is usually required. In this arrangement, a second semiconductor encapsulates the nanocr
