Quantum Dot Redox are extremely small semiconductor structures, usually ranging from 2- 10 nanometers (10-50 atoms) in diameter. At these small sizes materials behave differently, giving quantum dots unprecedented tunability and enabling never before seen applications to science and technology.

Quantum Dot Redox are a new type of environmentally friendly “green” semiconductor nanomaterials; as broadband gap semiconductor material, ZnSe is an important material to make blue green band semiconductor light-emitting devices. Synthesized using our proprietary technology, our Quantum Dot Redox have uniform size distribution, high quantum yield, and high stability, can be used in optoelectronic devices, solar cells, biomarkers, and other fields.

Liquid crystal display (LCD) dominates the TV and mobile electronic products market. Most if LCD devices use white light-emitting diode (W-LED) as the backlight to realize the display function, but suffer the drawbacks of inaccurate color saturation, and chromatography towards to blue light component side. While using the QD displays LCD can produce a wider color gamut and high saturation of primary color, and more accurate color performance. In addition, QD LCDs significantly reduce energy consumption and production cost.

InP is the best investigated III-V QDs. Regarding their bulk band gaps of 1.35 eV, InP QDs are considered as the most viable alternatives to Cd-based QDs for visible wavelength emission. Due to their large excition bhor radius, high extinction co-efficiency, board range of emissions that covering the whole visible range and extends to the near infrared, and containing no heavy metal elements, InP QDs have great potential to be used in flat panel display backlighting, QD-LED, lighting devices, biomedical markers, fingerprinting, and solar cell applications.

Size-dependent fluorescence properties are probably the most unique and attractive feature of QDs. For instance, through controlling the particle size from 2-6 nm, the emission from CdSe QDs can be continuously tuned to from green to red that covers entire visible wavelength range. However, there are two issues associated with the fabrication and application of binary QDs such as CdSe. First, the formation of defects and surface-trap states that result in the low luminescence efficiency and stability deficits. Although this problem can be minimized through nanocrystal surface-passivation with high bandgap inorganic material such as the most commonly used ZnS, the largely lattice mismatch between the core nanocrystal and passivation shell layer usually degrade the optical properties. Second, the extinction coefficients of QDs is also size-dependent – proportional to the volume of the particle. This means species that labelled with 2 nm green emitting QDs.
