Gold nanoparticles were studied with resonance scattering spectroscopy and trans mission electron microscopy.When the concentration of gold nanparticles with d=10 nm is less than 35.4×10^-6 g/mL,there are a max absorption peak at 525 nm and a resonance scattering peak at 525 nm.When the concentration of gold nanparticles with d=50 nm is less than 17.7×10^-6 g/mL,there are a max absorption peak at 530 nm and a resonance scattering peak at 530 nm.When the concentration of gold nanoparticles is higher,there are red-shift of resonance scattering peak and resonance scattering quenching.On the basis of the interaction between the excited photon and the interface electron of nanoparticles,as well as the multi-scattering occured due to the interaction between photons and nanoparticles,the relationship between resonance scattering and resonance absorbance,the red-shift and quenching of resonance scattering peak were studied.
