Synthesis and characterization of Lead Selenide quantum dots for photovoltaic application

Lead Selenide (PbSe) quantum dots (QDs) with absorption in the NIR region are synthesized in a non-coordinating solvent, octadecene by organometallic synthesis procedure. The high resolution transmission electron microscopy (HRTEM) analysis demonstrated spherical shape and monodispered nature of PbSe Quantum dots. Absorption spectrum demonstrates that the QDs show absorbance in the near infrared (NIR) region. The synthesized QDs give a good dispersion in n-hexane.
