Quantum Dots
Quantum dots are semiconducting nanocrystals, typically ranging between 2 and 10 nanometers in diameter (10-50 atoms), that can convert an incoming spectrum of light into a different frequency of energy output. These man-made crystals are made small enough that quantum mechanical effects emerge. Quantum dots have unique electronic optoelectronic properties that allows for tunability of energy levels with their wavelength or color. The particles can be made to emit or absorb specific wavelengths of light through tailoring of their physical dimensions. As quantum dots increase in size, the emission color will have a red spectral shift.

Inorganic Quantum Dots
We offer a variety of quantum dots, including core-type, core-shell, and alloyed quantum dots. Core type particles are composed of a single material, such as a chalcogenide. Core-shell quantum dots consist of a semiconducting core material and a distinct semiconductor shell, such as ZnS, which is used widely to achieve high quantum efficiency and stability. Finally, alloyed quantum dots maintain their size while tuning the optical properties via homogenous and gradient internal structures.
Inorganic quantum dots offer a continuous absorption spectrum and better photostability as compared to conventional molecular dyes. With spectral ranges from UV to NIR, our quantum dots are available in easy-to-handle solutions of water or toluene solvent, and in a wide range of surface functionalization for bioimaging applications, including common chemistries such as carboxyl, amine, and succinimidyl 4-(N-maleimidomethyl)cyclohexane-1-carboxylate (SMCC).
Carbon-based Quantum Dots
Carbon-based quantum dots display many advantageous properties in addition to quantum confinement and edge effects, such as high biocompatibility, water solubility, facile chemical modification, and catalytic properties. Types of carbon-based quantum dots include graphene quantum dots (GQDs) and carbon quantum dots (CQDs). GQDs are graphene structures (sp2-hybridized carbon) composed of several layered sheets with lateral dimensions less than 100 nanometers. CQDs are comprised of a disordered sp2- and sp3- hybridized carbon structure similar to amorphous carbon and have physical dimensions of less than 10 nanometers.
Perovskite Quantum Dots
Perovskite quantum dots (PQDs) are semiconducting materials with high luminescent efficiency. They have a low threshold, tunable wavelength, and ultra-stable stimulated emission (SE). These semiconductors are a class of hybrid organic-inorganic metal halide based perovskite materials, with the common formula ABX3, where A is Cesium (Cs) or FA (formamidinium), X is Chlorine (Cl), Bromine (Br), or Iodide (I). They have a direct bandgap which is useful for a variety of optoelectronic devices.
