Shelling dodecanethiol ligand quantum dots with silica to stabilize in water-based reactions

Research Mentor(s)

David Rider

Description

The purpose of this project is to encapsulate copper-indium disulfide-based quantum dots within a thin shell of silica. This method of shelling will cause the quantum dots to stabilize and retain their optical properties. Then when the silica shelled quantum dots are inserted into another reaction, they will maintain their composition and other properties. This becomes important for water-based reactions, like emulsion polymerizations, because the quantum dots will become “quenched”-- losing optical properties and aggregating--gaining size-- when introduced to water. By shelling the outer part of the quantum dots with silica, it is hypothesized that this should prevent “quenching” from happening, which will make them sustain in water-based reactions.
