Effect of Silver/Silcon Dioxide Film on the Infrared Absorption Properties of Sodium Nitrate
Silver/silicon dioxide (Ag/SiO2) film, which was used for surface enhanced infrared absorption spectroscopy, was made by mixing ammonia solution and SiO2 solution. Surface morphology of thin films was depicted by scanning electron microscopy, X-ray diffraction and ultraviolet-visible absorption spectrum. The present paper studies the spectroscopy of Ag/SiO2 film during the evaporation of water. Research results show that the anti-symmetric vibration absorption peak of nitrate is the function of solution concentration and the distances. Influence of surface enhanced infrared absorption spectroscopy in nitrate absorption peak is via the electromagnetic mechanism and increasing the effective surface area.
