| Fig. 3. Size versus band gap of the PbS NCs. The theoretical results are obtained by the semiempirical tight-binding method [ 21 ] #cod#x25A1; and the cluster model [ 23 ] #cod#x25B3;. The previous experiments were carried out by Moreels et al . [ 24 ] #cod#x25A0; and Wang et al . [ 23 ] #cod#x25B2;, respectively. The two red dots are of the two large NCs in the present work as measured by TEM . The red two-headed arrowheads show results for the two smallest NCs. |
