Zinc Oxide Quantum Dot INK DMAC

SKU: N/ACategory:

Zinc Oxide Quantum Dots-based ink (ZnO-DMAC ink) 

High-quality Uncoated Zinc Oxide Quantum Dots Nanocolloid
Monodispersed, narrow size distribution, solution-stable, bright yellow luminescence upon excitation with UV. 

  • Superior nanocrystal quality in comparison to sol-gel derived ZnO QDs
  • Superrior nanocolloidal solution –  no agglomeration in time
  • Lack of bulky organic coating – excellent electrical contact
  • No surface defects – improved charge separation and stability
  • High-purity ZnO Nanoparticles without any added process metal impurities
