ABSTRACT

I. INTRODUCTION The synthesis of monodisperse nanometer-size nanoparticles is of great technological and scientific interest. Quantum size effects are particularly of interest because they lead to interesting mechanical, chemical electrical, optical, magnetic, electro-optical, and magneto-optical properties that are quite different from those reported for bulk materials [1-4]. Nanoparticles not only are of basic physical interest but also have resulted in important technological applications, such as in catalysts, high-performance ceramic materials, microelectronic devices, and high-density magnetic recordings [5-7].
