Abstract

Ultra-small CdSe quantum dots (QDs) were synthesized by using reducing agent in ethylenediamine solution at mild temperature. Various reaction conditions of different precursor concentration, reaction temperature, and reducing agent were applied for the synthesis control of CdSe QDs. The control experiments resulted in two distinctively different sizes of ultra-small CdSe QDs of which the existing ratio was governed by the reaction factors of temperature and precursor concentration.
