Influence of Complexing Agents on Structural Properties of PbS Thin Films Prepared by CSD Method

Abstract

In this work, the influences of complexing agents and their molar concentrations on the structural properties of lead sulfide (PbS) nanostructures prepared by chemical solution deposition (CSD) method were studied. Other experimental parameters, such as concentration of reactants, pH of solution and bath temperature, were kept constant during deposition process. The structure of the prepared samples was analyzed by x-ray diffraction (XRD). It was found that the structural form of PbS nanorods is strongly influenced by the complexing agent and its molar concentration as an improvement in the structural quality was observed with changing the concentration of the complexing agent. However, too high concentration of complexing agent could lead to the degradation in the structural quality of the prepared samples.
