Figures / Tables:

Figure 1. Figure 1.: Optical characterization of the co-doped (in red) and intrinsic Si NCs (in black). (a) PL spectra taken at an excitation wavelength of λexc = 405 nm, displaying a significantly red-shifted PL spectrum for the co-doped ensemble as a result of the donor−acceptor-pair recombination process, as discussed in themore » main text. The dashed lines function as guides to the eye and represent Gaussian (red) and log-normal (black) fitting curves. (b) Linear absorption spectra indicating the charge carrier absorption feature for the co-doped Si NC ensemble. The dashed lines function as a guide to the eye. (c) XRD pattern of the co-doped Si NCs, showing two main components, the SiO2 band and the (111) Si peak. The dashed red line represents the total fitting function of the XRD pattern as elaborated in the main text. Similar PL and identical absorption data have been presented for these materials in refs 10 and 15.« less
