The surface plasmon of AuNPs influences the optical and photocurrent properties of the heterojunction considerably. Improvement in the band gap emission of TiO2 has been found at the expense of defect radiation. Excitation of AuNPs deposited on nSiNWs/TiO2 by light irradiation shows a wavelength-dependent photocurrent due to the increased photoactivity of the heterojunction.</p>1 aYenchalwar, Sandeep, G.1 aAzhagan, Muniraj, Vedi Kuyil1 aShelke, Manjusha, V.  uhttps://library.ncl.res.in/content/enhanced-photoluminescence-and-photoactivity-plasmon-sensitized-nsinwstio2-0
