Growth mechanism, shape and composition control of semiconductor nanocrystals

Abstract

In the last few years the development of colloidal nanocrystals has been extended from the pure adjustment of the size of the particles to the control of more sophisticated properties as their shape and composition. The hope is that through these features different fields of applications might be opened for the use of nanocrystals. In this chapter we will introduce a concept for the preparation of colloidal nanocrystals with a narrow size distribution and then discuss the shape control of colloidal nanocrystals as well as a technique for composition control, i.e. the formation of hybrid materials. © 2008 Springer-Verlag/Wien.
