【 摘 要 】

Series of Au colloidal solutions with different diameters were synthesized by the chemical reaction method. The influence of Au nanoparticles with different size on SERS of R6G was investigated. Experiments indicate that the enhancement factor grows in direct proportion to size of Au nanoparticles within limit.
