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.
