Abstract
The assembly is made up of: a) a support including a mesoporous coating whose pores have an average diameter dimensioned so as to enable molecules from the family of cyanines to penetrate them, and b) a layer of molecules from the family of cyanines and organized into J-aggregates within the pores of the coating. The assembly moreover includes Quantum Dots located within the same pores as those containing the J-aggregates, the Quantum Dots maintaining J-aggregates structure. A method for producing such an assembly is also described.
Claims20
An assembly comprising
- a support;
- and
- a mesoporous coating on the support, wherein the mesoporous coating comprises pores,
- wherein cyanine molecules are organized into J-aggregates at least within the pores of the mesoporous coating, wherein the pores have an average diameter that enabled the cyanine molecules to diffuse into the mesoporous coating;
- and
- wherein said assembly moreover comprises Quantum Dots located within the same pores as those containing the J-aggregates, the structure of said J-aggregates being maintained in the presence of said Quantum Dots.
