The crystallinity of a nanoparticle has a profound effect on its optical, electronic and chemical properties. Being able to control these properties is particularly important for advanced applications.
This technology makes it possible to control the number of metallic nanoclusters decorating a metalloid nanoparticle. The nanoclusters induce localized crystallization of the metalloid quantum dot. Further, if the metallic nanoclusters are not required for the application they can be removed without affecting the crystallinity of the quantum dot.
- Nanocluster materials can be selected from Al, Au, Ni, Pd & Cu
- Quantum dot materials can be selected from Si, Ge & SiGe
- The number of nanoclusters and therefore crystallites is controllable
- Metallic nanoclusters can be removed without affecting the crystallinity of the quantum dot
This technology is applicable to the specified materials. It may however, be possible to substitute other materials.
- Hydrogen storage
- Multimodal bio-imaging
- Optoelectronic devices
