摘要：

A new method was performed to prepare silver-coated cellophane paper substrates, and the influence of reaction time on the morphology and performance of the substrates were studied via SEM and Raman scattering techniques. The SERS activity including sensitivity, uniformity, reproducibility and stability of the cellophane paperbased substrates were analyzed. The cellophane paper-based substrates were applied for detecting Rhodamine 6G (R6G) in tap water, lake water, rain water and chili powders. Using the prepared SERS substrates, as low as 10(-11) M R6G in water samples and 10(-10) M R6G in chili powders can be detected respectively. The results proved that the as-prepared cellophane paper-based substrates were suitable for detection of R6G with low concentrations in real samples.
