Pulsed Laser Ablation based Direct Synthesis of Single‐Wall Carbon Nanotube/PbS Quantum Dot Nanohybrids Exhibiting Strong, Spectrally Wide and Fast Photoresponse (Adv. Mater. 47/2012)

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.
