Pulsed laser ablation for the direct synthesis of single‐wall carbon nanotube/PbS‐quantumdot(SWCNT/PbS‐QD) nanohybrids is demonstrated. The latitude of the developed pulsed laser deposition process permits not only the control of the size of the PbS‐QDs but also the straightforward integration of these novel SWCNT/PbS‐QD nanohybrids into photoconductive (PC) devices. Thus, by optimizing the nanohybrid characteristics, PC devices exhibiting not only fast but also strong photoresponse (as high as 1350% at 405 nm) are achieved.
