Direct formation of PbS nanorods in a conjugated polymer
A study was carried out to demonstrate that PbS nanorods can be directly assembled in a conducting polymer. The controlled assembly of the nanorods has been reported through oriented attachment of PbS nanocrystals using a post-synthesis treatment of PbS nanocrystal/poly(2-methoxy-5-(2'-ethyl-he...

| description | A study was carried out to demonstrate that PbS nanorods can be directly assembled in a conducting polymer. The controlled assembly of the nanorods has been reported through oriented attachment of PbS nanocrystals using a post-synthesis treatment of PbS nanocrystal/poly(2-methoxy-5-(2'-ethyl-hexyloxy) -p-phenylene vinylene) (MEH-PPV) composites synthesized by a low-temperature and surfactant-free method. The composite has broad optical absorption and the results of the experimentation have also shown that the nanorods formation is governed by the polarity of alcohol used for precipitation. This formation also appears to arise from dipole-induced oriented attachment of PbS nanocrystals. The results of the study also have found that the extension of the composite absorption beyond the main polymer exciton peak at ca. 520 nm is due to the presence of nanocrystals. |
