摘要：NOVELTY - A surface-enhanced raman scattering substrate preparing method involves preparing liquid reagent by adding hydrogen peroxides, peroxide decomposition catalyst, PH adjusting agents, ionic strength modifiers prepared by free radical generators in solvent, allowing a metal foil for surface treatment. The surface treated metal foil is placed in liquid reagent at 5-180 degrees C under atmospheric pressure of air or pure oxygen, followed by allowing for auxiliary or secondary illumination under sonication, and soaking the substrate to obtain the finished product. USE - Method for preparing surface-enhanced raman scattering substrate. ADVANTAGE - The method enables preparing surface-enhanced raman scattering substrate in simple, fast and controllable manner. DETAILED DESCRIPTION - A surface-enhanced raman scattering substrate preparing method involves preparing liquid reagent by adding hydrogen peroxides, peroxide decomposition catalyst, PH adjusting agents, ionic strength modifiers prepared by free radical generators in solvent, allowing a metal foil for surface treatment.
