Summary of the technology

core-island-shell nanocrystals
Project ID : 14-2018-4648

Description of the technology


  • Nanocrystals can be used as a building blocks of nano-devices in diverse applications such as solid- state lighting, flat panel displays, solar energy conversion, opto-electronic devices and biomedical applications.
  • Colloidal semiconductor nanocrystals are a class of nanomaterials that manifest the transition from the molecular limit to the solid state.

Our innovation

A new architecture for colloidal semiconductor nanostructures (specific compositions), based on known semiconductor crystal growth mechanisms.


  • Fabrication of heavy-metal free semiconductor nanocrystal heterostructures was demonstrated.
  • It was shown that lattice mismatch between the different materials can impact useful chemical catalytic properties
  • The formation of island morphology is critical for the technological beneficial properties of this system


  • Photocatalytically stable
  • General method which not limited to one specific technology use
  • Heavy-metal free quantum dots and quantum materials
  • Potentially effective in areas related to photochemistry, energy systems and phototherapy
  • The architecture could be used as a photoinitiator for UV curing systems
