Resonance Scattering Spectroscopy of Fluid Carbon Naoparticle
Abstract:
It was found that for chinese ink carbon nanoparticle there were four resonance scattering peaks at 400 nm, 470 nm, 510 nm and 940 nm when its concentration was less than 360 mg/L . When c(C) was more than 0.9 g/L, no resonance scattering peak was observed. A linear dependence between intensity I470 nm and the concentration of carbon particles ranged in 0.45~45 mg/L was found. The effects of lamp source and the scanning rate on the RSS of carbon nanoparticle were investigated. The results showed that the difference in distribution emission intensity of lamp source appeared one of important factor to produce resonance scattering peaks. It is explained in terms of interface resonance absorption and resonance emission of white and black carbon nanoparticle in ink.
