Zinc Oxide Quantum Dot INK DMAC

- Overview
  - 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
