A Study on Core Shell Quantum Dots NPs

Nanotechnology

Core/Shell quantum dots are products of further engineering in the structures of quantum dots (QDs). A QD has a high surface area to volume ratio with unsaturated bonds, or dangling bonds, existing on the surface. These under-coordinated atoms make them more active than those in the bulk of the QD materials. Core-shell type nanoparticles are a type of biphasic materials which have an inner core structure and an outer shell made of different components. These particles have been of interest as they can exhibit unique properties arising from the combination of core and shell material, geometry, and design.

A QD has a high surface area to volume ratio with unsaturated bonds, or dangling bonds, existing on the surface. These under-coordinated atoms make them more active than those in the bulk of the QD materials.Core-shell nanostructures can be defined as nanoparticles, which are encapsulated and covered by an exterior shell, which provide stability to the core nanoparticles against agglomeration and coalescence, which might happen during any type of reaction.
