Synthesis and Characterization of Fe Doped CdS Quantum Dot

Abstract

Transition metal ion doped quantum dots finds their wide range of use in the field of photonics and photovoltaics. In this research work, CdS quantum dots, with Fe ion doping, are synthesized using simple One Pot Synthesis chemical method. The polymer matrix used in the synthesis is Polyvinyl Alcohol (PVA) matrix, which restricts the size of quantum dot while not itself participating in the reaction. Three doping concentrations are 3%, 6%, and 9%, by weight of Fe have been used for doping of CdS. The synthesized quantum dots are also analyzed using Ultraviolet Visible (UV-Vis) Absorption, X-Ray Diffraction (XRD), and HRTEM microscopy to study their optical and crystallographic properties.
