NOVELTY - Obtaining high efficiency fibrous Raman scattering (SERS) substrate involves using silver flower rich in nano-gap on fibers such as graphene. The beaker is selected as the reaction vessel, and fiber is suspended and immersed in the reaction solution. The immersed solution is placed under conditions of ice water bath and magnetic stirring, the reaction reagent is added to the beaker sequentially to control reaction for 5 minutes, and the reaction is quickly stopped with a large amount of ice water. The fiber is removed and rinsed with deionized water/ethanol, dried, and stored. USE - Method for obtaining high efficiency fibrous Raman scattering (SERS) substrate. ADVANTAGE - The method enables to obtain high efficiency fibrous Raman scattering (SERS) substrate, which has fast and high production efficiency, and good mechanical stability, and is processed in simple and cost-effective manner. DETAILED DESCRIPTION - Obtaining high efficiency fibrous Raman scattering (SERS) substrate involves using silver flower rich in nano-gap on fibers such as graphene. The beaker is selected as the reaction vessel, and fiber is suspended and immersed in the reaction solution. The immersed solution is placed under conditions of ice water bath and magnetic stirring, the reaction reagent is added to the beaker sequentially to control reaction for 5 minutes, and the reaction is quickly stopped with a large amount of ice water. The fiber is removed and rinsed with deionized water/ethanol, dried, and stored. The change of reaction conditions, and efficient fibrous SERS substrate is successfully obtained by replacing ice-water bath and magnetic stirring conditions at normal temperature and stirring.
