Abstract

Abstract: We study a cost effective and easy way to fabricate stable, uniform and large area surface-enhanced Raman scattering (SERS) substrates. The AgNPs with varying diameters have been fabricated through a thermally treating method on SiO2 /Si substrate which present a high sensitivity, good uniformity and good stability. By using rhodamine 6G (R6G) molecule as analyte, the maximized detection limit is as low as 10 −8 M. The deviation of SERS intensity by using proposed AgNPs SERS substrate is less than 15% which indicates its good uniformity. This work provides an efficiently way of fabricating industry SERS substrates which are good candidate in practical application in medicine, food safety and biotechnology.
