Abstract

The synthetic procedure of the growth of one semiconductor material (PbS) on a seed of another (TiO₂) have been developed. The contact between TiO₂ and PbS quantum dots was characterized by optical absorption and fluorescence. The dramatic increase of the bandgap of PbS (ΔE_g=1.5 eV) was observed after precipitation of PbS in the colloidal solution of TiO₂. The positions of the lowest empty energy level of TiO₂ and PbS single quantum dots as well as TiO₂-PbS composite were determined by pulse radiolysis technique. The contact between TiO₂ and PbS quantum dots leads to the transfer of electrons from PbS to TiO₂.
