The Synthesis of Core/Shell Quantum Dots
Quantum dots have desirable optical properties, yet often require further stabilisation to provide novel optical properties and to be practically useful. In this chapter we describe shelling chemistries and techniques, and the types of structures accessible, such as type I, type II and inverse shell heterostructures. We also discuss the use of alloys in core/shell chemistry, the more unusual shell materials and the use of multiple shells. We extend our discussion to core/shell materials based on III–V and IV–VI quantum dots.
