(a) Sketch and (b) photograph of the experimental setup for microplasma processing of the SiNCs/ethanol colloidal dispersion.
FTIR transmission spectra of the dried SiNCs before and after processing. Spectra have been normalized to the local minima.
PL spectra of SiNCs dispersed in ethanol before and after processing at different processing time (16 and 80 min, open symbols). PL emission after 5 days from processing. The inset shows the summary details of the PL intensity maxima (open rhombuses) and corresponding wavelength (full black squares).
(a) SEM image of the SiNCs self-organized networks obtained after microplasma treatment. (b) Current voltage characteristics of the corresponding self-organized networks. Open symbols represent measurements in dark and line is the same measurement taken under AM1.5 irradiation.
