ABSTRACT The hot-injection is one of the most used chemical synthesis methods to be able to produce nano- and/or micron
sized particles in a liquid medium. Synthesis of nanoparticles of group II-VI semiconductors such as ZnO, ZnSe, CdSe and IV
and V metals such as Pb, Sn, Bi has been achieved successfully with this method. The synthesis of CdSe and Bi particles
including both their nano-sized forms such as nanocrystals, nanoplates and nanowires and also the micron-sized forms
obtained via hot-injection is exhibited in this study. Transmission electron microscopy (TEM) images of these nanostructures
are supported by their energy dispersive X-ray (EDX) measurements. The X-ray powder diffraction (XRD) is used to
determine their composition. The crystal structure of the Bi microparticles is determined. The classical growth model of the
colloidal nanoparticles is given. Some superior aspects of this synthesis procedure relative to the others are shown and
discussed with the help of the experimental findings.
