Abstract
New efficient surface enhanced raman scattering (SERS) nanocomposite material namely silver nanoparticles (AgNPs) decorated Cerium Oxide (AgNPs@CeO2) was synthesized by adopting simple citrate reduced, precipitation and deposition methods. The synthesized AgNPs@CeO2 material was characterized with UV-DRS, FTIR, Raman, FESEM, EDX and HRTEM analyses. The obtained results reveal the formation of AgNPs@CeO2 nanocomposite material with high purity. The FESEM image result confirms that the Ag NPs are decorated on the surface of CeO2. This AgNPs@CeO2 nanocomposite was used for fabrication of SERS substrate by drop casted on glass slide. Similarly, for comparative purpose, the pure AgNPs and CeO2NPs were also fabricated individually on glass slide. The SERS properties for newly fabricated AgNPS@CeO2, AgNPs and CeO2 NPs substrate were examined by employed in to detection of 4-aminothiophenol (4-ATP) as a model Raman reporter molecule/analyte. The newly designed AgNPs@CeO2 material showed excellent SERS properties and sensitivity than that of AgNPs and CeO2NPs substrates. The enhanced SERS properties noticed in AgNPs@CeO2 are due to the charge transfer, electromagnetic effect and more hot spots present in metal on metal oxide surfaces. Therefore, it is suggested that the AgNPs@CeO2 composite material with excellent SERS properties will have an intensive scope for detection of medically significant single analyte/molecule and hence study in that direction are continuing.
