摘要
Cap-like α-Fe2O3 films are fabricated and deposited onto quartz fabric by using radio frequency magnetron sputtering and annealing.The treated fabric sample in this study shows highly sensitive surface-enhanced Raman scattering (SERS) and excellent flexibility,reproducibility and stability.In addition,the sample can be recovered after a washing process with an organic solvent and repeatedly used.The sensitive SERS performance is attributed to chemical enhancement through a charge transfer process.Moreover,the SERS performance is also found to be dependent on the light coupling effect.When the light absorbance rate of the α-Fe2O3 films increases at a wavelength near that of laser light,the film shows excellent sensitivity due to light coupling effect.
