Table 1 Results of non-linear least-squares curve fitting analysis for the Pb and Hg L3 edge spectra of the PbS and PbS:Hg QDs adsorbed on TiO2 with different HgCl2 concentration. Bulk PbS and HgS are references. CN, R and σ2 represent coordination number, interatomic distance and Debye-Waller factor
