Abstract—A novel approach to preparing PbSe quantum dots in a high-boiling-point solvent (paraffin liquid)
was studied. PbSe quantum dots obtained were transferred from the organic phase to aqueous phase. The PbSe
samples were characterized by transmission electron microscopy, X-ray diffraction, and energy dispersive
Xray analysis, which demonstrated that high-quality PbSe quantum dots with regular shape and uniform size
were prepared. The mechanism of PbSe quantum dot formation was briefly discussed.
