Quantum dots are a unique class of semiconductor particles, ranging from 2-10 nanometers (10-50 atoms) in diameter. At these small sizes, materials behave differently, giving quantum dots unprecedented tunability and enabling applications to exploit unique properties at the nanoscale.

The usefulness of quantum dots comes from their peak emission frequency’s extreme sensitivity to both the dot’s size and composition, which can be controlled using Unique Technologies’ proprietary manufacturing techniques, control over surfaces and ability to incorporate the quantum dots in common matrix materials, polymers and resins.
The Advantages of Core and Core-Shell Quantum Dots

Narrow Fluorescent Emission – We produce fine spectral resolution due their narrow full width half max (typically
< 30nm for CdSe/ZnS Quantum Dots).

Color Tunability – XBH are available in multiple emissions from 465nm (visible) to 2300nm (infared).

Broadband Absorption Source – XBH have a broader absorption profi le compared to traditional organic dyes & phosphors

Less overlap between adjacent colors – XBH reduce cross-talk between crystals of different colors because each color is emitted as a narrow, symmetrical, fl uoresence peak. The peak excitation wavelength does not overlap with emission wavelength.
