摘    要:液相碳纳米微粒的共振散射光谱实验表明,当碳浓度小于360mg/L时,它在400、470、510和940nm产生4个共振散射峰;浓度大于900mg/L时无共振散射、碳微粒浓度在0.45-45mg/L范围内与共振散射光强度I470nm成良好的性关系,研究了光源和扫描速度对液相碳纳米微粒共振散射光谱的影响。结果表明,光源的发射强度分布不一是产生共振散射光谱峰的一个重要因素,并结合已有的实验结果提出了界面共振吸收和黑白纳米微粒共振散射概念,解释了碳纳米微粒体系的共振散射光谱。

关 键 词:黑白粒子  碳纳米微粒的共振散射光谱研究

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 I 470 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.
Keywords:carbon nanoparticle  white particle  black particle  resonance scattering spectroscopy
