Highly luminescent flexible CdSe/ZnS‐clay films with a well‐organized structure can be prepared by simple casting of aqueous dispersions of nanocrystals and clay. Through electrostatic interactions, negatively charged CdSe/ZnS nanocrystals are incorporated into the spaces between the positively charged edges of clay platelets. A substantial enhancement in photoluminescence efficiency is observed by introducing thermal annealing.
