Synthesis and Characterization of PbS Quantum Dots
Colloidal semiconductor nanocrystals or quantum dots (QDs) have recently attracted much attention because of their unique electronic and optical properties and potential for a wide range of applications. Near-infrared (NIR) PbS QDs were synthesized using oleic acid (OA) as a surfactant for stabilizing the nanocrystals. PbS QD’s of different diameters were obtained by varying the injection temperat
