Cadmium Sulfide Thin Films Deposited onto MWCNT/Polysulfone Substrates by Chemical Bath Deposition

Figure 3

Optical characterization of a representative CdS thin film deposited by CBD. (a) Absorbance spectra of the MWCNT/PSF substrate (dashed line) and of the CdS/substrate system (solid line) as a function of the wavelength, (b) absorbance spectrum of the CdS/film obtained by subtracting the reference spectrum (substrate), and (c) versus energy () plot obtained from data of Figure 3(b). The straight line in the linear portion of the plot is included for clarification purposes.
