摘要
In this work, thermal stabilities of electrochemically prepared surface-enhanced Raman scattering (SERS)- active gold and silver substrates were first investigated. The results indicate that the SERS enhancement capabilities of gold and silver substrates are seriously destroyed at temperatures higher than 200 and 125 °C, respectively. Further experiments reveal that the decrease in SERS enhancement capability mainly comes from the decrease of the chemical (CHEM) enhancement for gold substrates. However, the decrease in SERS enhancement capability can be ascribed to the decreases of both the electromagnetic (EM) enhancement and the chemical (CHEM) enhancement for silver substrates.
