LIGHT RAMAN SCATTERING ENHANCEMENT BY INORGANIC PIGMENTS WITH THE USE OF GOLD AND SILVER NANOPARTICLES
Abstract
In this paper different techniques of surface enhanced Raman scattering (SERS) by inorganic art pigments have been tested. Every pigment has each own dependence of the enhancement factor on nanoparticles sizes. The relative position of analyte and metal nanoparticles has no significant impact on the value of the enhancement factor. However, applying nanoparticles on top of the pigment is the most simple and less time-consuming method for sample preparation. In addition, the use of gold and silver nanoparticles provide comparable values of the intensity in the SERS spectra, but the use of gold nanostructures allows reducing the fluorescent background. So, the interpretation of spectra becomes easier.
