Abstract
To fabricate the dispersed and uniformed PbS QDs, mercaptoacetic acid and centrifugation were investigated in the process of reaction which was to synthesize QDs. The TEM and PL experiments showed that we succeeded in chemical synthesis of PbS QDs which generate photoluminescence (PL) with very weak polarization dependence. Emission wavelength range of the QDs covered 1.3 ¿m. Influence of the synthetic conditions on PL polarization characteristics and the QD structure was investigated.
