Application

Uses:
  • Preparation of flexible transparent conductive coatings essential for fabrication of a variety of printed electronic devices such as flexible displays and solar cells
  • Prepare a composite CdS-ZnS/Zirconium-titanium phosphate (ZTP) photocatalyst for hydrogen production under visible light
  • Prepare light-controlled bioelectrochemical sensors based on CdSe/ZnS quantum dots
  • Catalyst for photocatalytic degradation of organic pollutants
  • Preparation of color tunable light-emitting diodes (LEDs)
  • Prepare (CdS-ZnS)-TiO2 combined photocatalysts for electricity production via photoelectrocatalysis
  • Catalyst for synthesis of spirooxindole derivatives in aqueous medium via Knoevenagel condensation followed by Michael addition
  • Prepare CdSe/ZnS q uantum dots for chemiluminescent and chemiluminescence resonance energy transfer (CRET) detection of DNA, metal ions, and aptamer-substrate complexes
  • Preparation of ZnS nanocrystals for ultrasensitive protein detection in terms of multiphonon resonance Raman scattering
Zinc sulfide finds applications in anti-reflection coating. The use of anti-reflection coating using ZnS has been known to increase the effeiciency of solar cells as well.
