Quantum dots represent nanoscale semiconducting crystals, typically spanning 2 to 10 nanometers in diameter (equivalent to 10-50 atoms), capable of transforming incoming light spectra into different energy output frequencies. These artificially engineered crystals attain a size where quantum mechanical effects become prominent. Characterized by distinctive electronic and optoelectronic traits, quantum dots offer the ability to tune energy levels based on their wavelength or color. Manipulation of their physical dimensions enables these particles to emit or absorb specific light wavelengths. As quantum dots increase in size, their emission color experiences a red spectral shift.

Inorganic Quantum Dots:

Our offerings include diverse quantum dot types, including core-type, core-shell, and alloyed quantum dots. Core-type particles consist of a singular material, like a chalcogenide. Core-shell quantum dots combine a semiconducting core with a distinct semiconductor shell, often ZnS, ensuring high quantum efficiency and stability. Alloyed quantum dots maintain size while tuning optical properties through uniform and gradient internal structures. Compared to conventional molecular dyes, inorganic quantum dots offer continuous absorption spectrums and improved photostability. Spanning UV to NIR ranges, our quantum dots come in user-friendly solutions of water or toluene solvents, with versatile surface functionalization options 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 not only exhibit quantum confinement and edge effects, but also present advantageous properties like high biocompatibility, water solubility, easy chemical modification, and catalytic activity. Varieties include graphene quantum dots (GQDs) and carbon quantum dots (CQDs). GQDs comprise layered graphene structures with lateral dimensions below 100 nanometers. CQDs consist of a disordered sp2- and sp3-hybridized carbon structure akin to amorphous carbon, with dimensions under 10 nanometers.

Perovskite Quantum Dots:

Perovskite quantum dots (PQDs) display high luminescent efficiency, low thresholds, tunable wavelengths, and ultra-stable stimulated emission. As hybrid organic-inorganic metal halide-based perovskite materials, they possess the formula ABX3, where A is Cesium (Cs) or FA (formamidinium), and X is Chlorine (Cl), Bromine (Br), or Iodide (I). With a direct bandgap, PQDs are useful for a range of optoelectronic devices.
