Size Tunable near Infrared High-Quality PbS Quantum Dots

Abstract:

Herein, we report the synthesis of PbS Quantum Dots (QDs) with oleic acid as surfactant molecules by non coordinating solvent route. The particles are having better size tunability by varying temperature and time of reaction. These quantum dots are characterized by optical absorption, photoluminescence and transmission electron microscopy. The resulting colloids are highly stable, extremely small size, spherical in shape, monodisperse and strong band emission. The estimated particles sizes are in the range of 2 to 6 nm. The present method of synthesis of PbS quantum dots can be used to fabricate low cost electronic devices.
