The composite PMMA films containing Ag nanoparticles and rhodamine 6G are prepared.We investigate the fluorescence Droperties and nonlinear optical properties of R6G/PMMA films influenced by Ag nanoparticles.The fluorescence enhancement factor is about 3.3.The corresponding nonlinear refractive index is measured to be-2.423×10-8 esu using the Z-scan technique,which is much enhanced compared with the R6G/PMMA film.The results indicate that these enhancements are attributed to surface plasmon resonance of Ag nanoparticles.
