A pulsed laser ablation based approach is developed on page 6289 by My Ali El Khakani and co‐workers for the direct synthesis of nanohybrid structures consisting of single‐wall carbon nanotubes (SWCNTs) decorated with PbS quantum dots (PbS‐QDs). By varying the laser ablation conditions, the size of the PbS‐QDs together with the coverage rate of the nanotubes can be controlled. The latitude of the laser ablation process allows the SWCNTs/PbS‐Qds nanohybrids to be easily integrated into photoconductive devices, which exhibit strong and fast photoresponse over a wide spectral range.
