| Semiconductor Quantum Dots have been the focus of intense research throughout the past two decades. It is the size dependant optical properties, and enhanced magnetic properties of these materials that have brought forth such interest in them. In this dissertation the synthesis of monodisperse, crystalline, Cd1-xCoxSe and Cd1-xCux Se quantum dots will be discussed. The precursors required for the synthesis will also be studied and discussed in detail. A question that arises often when doping nanomaterials is the location of the dopant ion. Effective analytical techniques for studying the location of the impurity atoms have been implemented and are discussed here (EXAFS, XANES, XPS, pXRD, ICP-AE). Using these methods the oxidation states of the dopants have been determined and it the site of the dopant can be assigned to the core of the quantum dot. |
