▎ 摘　　要

NOVELTY - Quick green synthesized graphene oxide-modified popcorn-like silver surface-enhanced Raman scattering (SERS) composite structure comprises 14-30 pts. wt. silver nitrate, 14-30 pts. wt. EDTA, 7-15 pts. wt. stannous chloride, 2-7 pts. wt. acetone, 5-15 pts. wt. anhydrous ethanol, 3-9 pts. wt. dilute sulfuric acid, and balance deionized water. USE - Quick green synthesized graphene oxide-modified popcorn-like silver SERS composite structure. ADVANTAGE - The structure is stable and uniform. The preparation method is repeatable. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for synthesizing the SERS composite structure comprising pretreating copper, ultrasonic washing with ethanol and deionized water for 2-3 minutes, adding dilute sulfuric acid for 4-6 minutes, washing with deionized water, adding stannous chloride solution, silver nitrate solution and EDTA, absorbing, tin for 10-12 minutes, removing acetone, drying, soaking in silver nitrate solution, and ultrasonic cleaning with deionized water and anhydrous ethanol.
