Figure 3.
Steady state transmission measurements carried out on SnO2NWs using a UV-IR spectrometer. The upper corner inset shows a plot of the square
of the absorption versus incident photon energy, providing us with an estimate of
the bandgap energy 3.77 eV. There are two broad absorption bands below the bandgap
referred to as D.T.S—deep trap states and S.T.S.—shallow trap states
