ZnO Quantum Dots and Nanoparticles of a Superior Quality

NANOXO Zinc Oxide quantum dots (ZnO QDs) are of unprecedented quality.

They have significantly better chemical and physical properties than their counterparts currently being produced by the most popular sol-gel method.



Organometallic approach

The organometallic approach developed by Nanoxo allows for manufacturing defect-free ZnO QDs with novel physicochemical properties such as long-term stability, monodispersity, a relatively high quantum efficiency, record-long luminescence lifetimes and EPR silence under standard conditions.

The unique features of the tightly coordinated and impermeable organic shells stabilizing the surface make the new ZnO quantum dots resistant to both chemical and biological environments

1. True, non-toxic, bio-safe
2. UV absorption up to 400 nm (depending on product version)
3. Luminescence lifetime up to µseconds
4. Tunable color emission (480 – 570 nm)
5. High quantum yield and brightness
6. Size tunable (2 – 10 nm)
7. Possibility of attaching custom chemical groups for further coupling (click chemistry)
8. Hydrophilic or hydrophobic (dependent on product version)
9. Long term stability
10. Do not aggregate into clusters
11. Different shapes
12. Scalability

High-quality Uncoated Zinc Oxide Quantum Dots (Nanoparticles)

1. Superior nanocrystal quality in comparison to sol-gel derived ZnO QDs
2. Well–soluble in DMSO – no agglomeration in time
3. Lack of bulky organic coating – excellent electrical contact
4. No surface defects – improved charge separation and stability
5. High-purity ZnO without any added process metal impurities
