Nanocrystal-functionalized Carbon Nanotubes for Broad Spectrum Photoharvesting |
| 초록 |
Carbon nanotubes (CNTs) and polymer nanotubes functionalized with quantum dots(QDs) have been studied recently as active materials in inorganicorganic hybrid photodetectors and photovoltaics. QDs act as efficient, band-gap tunable exciton generators active over full spectrum of solar radiation from UV-Vis to IR region of the spectrum depending on the size and materials. CNTs coupled with QDs also act as electron carriers that will separate and carry the electrons from the excitons generated at the QDs. In the presented work we describe the synthesis and characterization of nanocrystal-functionalized CNTs for broadband photoharvesting. We have employed a thiol terminated pyrene derivative as a spacer between the QDs and CNTs. We have achieved nanocrystal-CNTs nanocomposites which are broad band active by ligating the pyrene linker with all the different QDs described above and functionalizing them to the same CNTs. |
