FIG. 1.

(Color online) (a) PL spectra of the ultrathin cuboid SnO2 NC suspension excited by the 280-310 nm lines of a Xe lamp. (b) PL spectra composed of tow subpeaks acquired from the suspension and dried powder excited by 310 nm.

FIG. 2.

(Color online) (a) Typical HR-TEM image of the SnO2 NCs. (b) SAED pattern of the SnO2 NCs. (c) Sn 3d XPS spectrum of the SnO2 NCs. (d) Length distribution of the SnO2 NCs with lateral width D of 4.0 nm.

FIG. 3.

(Color online) Ultraviolet/visible absorption spectrum acquired from the SnO2 NCs. The inset shows the corresponding Raman spectrum.

Image of FIG. 4.
FIG. 4.

(Color online) Left: DOSs of the cuboid NC surfaces with OV distribution depths at d = 0, 0.314, and 0.627 nm and no vacancy. Right: Enlarged VBM region. Splitting of the VBM due to addition of OV can be clearly seen and it leads to splitting of the PL peak observed experimentally.

Image of FIG. 5.
FIG. 5.

(Color online) Left: DOSs of the cuboid NC surfaces with different OV types and no vacancy. Right: Enlarged VBM region. Splitting of the VBM due to addition of in-plane OV can be clearly observed. The bridging OVs do not cause the observed violet double-peak PL.
