Sn 3d3/2 of Sn 4+ in SnQDs, respectively. The intensity of the deconvoluted Sn spectra after the interval of 12 h is lower than that of 6 h and a minor shift of 0.22 eV is observed in case of the binding energies after exfoliation for 12 h. This is due to the deposition of Carbon over Sn which is confirmed by the increase of atomic percentage for carbon in C 1s spectra from 37.29 % to 41.03 % and also from TEM. The high-resolution C 1s spectrum in Figure ) presents two peaks The as-synthesized SnQDs have been used as an anode material for Lithium-ion batteries (LIBs).
