ABSTRACT
This chapter focuses on some of the most important issues of relevance to hybrid inorganic/organic devices making use of the quantum-confined electroluminescence and charge-transport properties of nanocrystals in general and cadmium chalcogenides in particular. It also focuses on the theory of quantum confinement in cadmium telluride nanocrystals to illustrate general concepts by one particular example, then the synthesis of processable cadmium chalcogenide nanocrystals and finally their assembly and use as the emissive material in flat panel electroluminescent devices. Cadmium chalcogenides have also been prepared in the aqueous droplets in reverse micelles in order to create nanocrystals of a defined size and spherical shape. The main alternative method for the synthesis of cadmium chalcogenides involves using aliphatic thiol and aromatic thiophenol stabilizers in colloidal, often aqueous, solutions.
