Nano-composite films of Tin Sulfide (SnS) and silver fabricated by thermal evaporation showed two prominent peaks in the visible region of their extinction spectra. Theoretical modeling of the extinction spectra suggests that these two peaks (approximate to 500 nm and approximate to 580 nm) correspond to the longitudinal mode and transverse mode surface plasmon resonance peaks arising from oblate silver nano-particles. Using grain size of silver and SnS obtained from structural and morphological characterizations of the samples and dielectric constants as per actuals, we have compared the experimental results with those from theory. The study shows that silver nano-particles efficiently scatters light and can be used for developing plasmonic based SnS solar cells with improved efficiencies. (C) 2014 AIP Publishing LLC.
