In this work we report on the shift in band gap and enhanced photoluminescence in SnS nanostructures by increasing the Sn concentration. We study the effect of metal ions on the nanostructures as highly degenerate structures with plasmonic properties. Sn metal ions present in SnS nanoparticles lead to blue shift in the band gap of SnS nanoparticles due to plasmon assisted interaction between the excitons. The influence of the plasmonic particles also assist in enhancing the photoluminescence (600 nm) by modifying the radiative states of SnS nanoparticles.It has potential application in photoconductors, near IR detectors, holographic recordings, photovoltaic materials, commercial sensors and biomedical monitoring.
