Abstract
Size-controlled CdS quantum dots are successfully synthesized in PVP matrix through chemical route. The obtained particles are characterized with XRD, UV/VIS and HRTEM. Nearly spherical and well dispersed particles of size 3-20 nm are obtained. The size of the prepared quantum dots can be readily tuned depending on temperature, stirring rate and concentration in the reaction system. This particle size produces a quantum confinement observed from blue shifted absorption edge at 211nm in UV/VIS absorption spectroscopy.
