不同电荷卟啉掺杂单壁碳纳米管
Doping single wall carbon nanotubes with differently charged porphyrins
摘要：
研究了卟啉掺杂单壁碳纳米管在十二烷基苯磺酸钠（NaDDBS）水分散体系中的光致发光（PL）。PL光谱被用来绘制PL图，其中最大值对应于与单壁碳纳米管电子结构的（E11，E22）第一范霍夫奇异性相关的吸收-发射激子过程。卟啉的净电荷的影响是一个决定性的因素，在能量图最大位移（EMMS）相比，一个原始的NaDDBS/SWNT分散体的能量图。一个非相互作用的卟啉被用来作为参考，以消除介质的介电常数的影响，在EMMS。
英文摘要：
Photoluminescence (PL) measurements of porphyrin-doped single wall carbon nanotubes (SWNT) were studied in sodium dodecylbenzenesulfonate (NaDDBS) aqueous dispersions. The PL spectra were used to draw PL maps were the maxima corresponds to absorption-emission excitonic processes related to (E11, E22) first Van Hove singularities of the SWNT electronic structure. The influence of the net charge of the porphyrin was a determinant factor in the energy map maximum shifts (EMMS) compared to the energy map of a pristine NaDDBS/SWNT dispersion. A non-interacting porphyrin is used as a reference to discard the influence of the dielectric constant of the medium in the EMMS.
