Zinc Oxide Quantum Dot INK DMSO-L

- Overview
  - Zinc Oxide Quantum Dots-based ink (ZnO-DMSO ink)
    Patented nanocolloidal dispersion of ZnO QDs in easily removable solvent molecules. Free from any organic stabilizing molecules and salt impurities allowing to cast pure ZnO thin films featuring no agglomeration, high crystallinity, stability, excellent electrical contact, and a low-density defects of ZnO. Recommended for fabrication of low-temperature processed non-passivated ETL layers in state-of-the-art devices with improved performance and enhanced operational stability.
    Monodispersed, narrow size distribution, solution-stable, bright yellow luminescence upon excitation with UV.
    • Superior nanocrystal quality in comparison to sol-gel derived ZnO QDs
    • Superior nanocolloidal solution - no agglomeration in time
    • Lack of bulky organic coating and organic stabilizing molecules - excellent electrical contact
    • No surface defects - improved charge separation and stability
    • High-purity ZnO Nanoparticles without any added process metal impurities
