We have developed a simple and versatile method to synthesize the gold nano-prism (AuNPr) by growing it through seed-mediation and thereafter separating it via sedimentation method. The grown AuNPr showed strong plasmonic resonance peak localized near NIR region. Apart from strong plasmonic effect, we also observed the non-linear optical behavior which has not been observed in metal nano-prism structure before. It was confirmed using photoluminescence(PL) spectroscopy where excitation wavelength of 825nm produced luminescence peak at around 525nm. To apply the dual properties of plasmonic effect and up-conversion emission, we fabricated various organic bulk heterojunction solar cells utilizing these AuNPr in different configurations.
