| 摘要 | Surface enhanced Raman scattering (SERS) is a highly sensitive spectral analysis technique for ultra-low trace molecule detection. Conventionally, noble metals like silver (Ag) and gold (Au) are used to prepare the SERS substrates; however, it usually requires careful experiment design and accurate process control, which defers their wide applications in practice. In this paper, a one-step and low-cost approach to prepare silver decorated porous carbon (Ag NPs/PCN) films for SERS application is reported. Experimentally, gelatin-silver nitrate mixed solution was first spin-coated on the Si substrates to form the thin films, and then, the substrates were carbonized at the different temperatures to obtain the Ag NPs/PCN films. The SERS performance of the Ag NPs/PCN films was evaluated by using the R6G as Raman reporter. Results reveal that the SERS activity is closely related to the spin-coating rate and carbonization temperature. And detection limit of 10 M with the Raman enhancement factor of 1.64 × 10 (10-M R6G) can be obtained on the most optimal substrate. Moreover, large-scale mapping measurement further evidences that excellent Raman signal uniformity with the RSD of 6.93% also can be achieved. |
