INRS develops a nanohybrid with remarkable properties using a new laser-plasma process
Date:1/25/2013

Montreal, January 25, 2013 By achieving the synthesis of a novel nanohybrid structure by means of the pulsed laser ablation (PLA) technique, Professor My Ali El Khakani and his team paved the way for a new generation of optoelectronic materials. The combination of carbon nanotubes and lead sulfide (PbS) nanoparticles was performed using an effective and relatively simple process that offers considerable latitude for creating other nanohybrids for a variety of applications. The INRS nergie Matriaux Tlcommunications Research Centre researcher's work, published in the renowned journal Advanced Materials, presents very promising prospects for the development of third-generation solar devices, fast photodetectors, and optoelectronic switches.

In recent years, research on the photoelectronic properties of semiconductor nanoparticles, such as PbS, has been growing. The coupling of these nanoparticles with carbon nanotubes is a promising strategy for effectively generating photocurrent. The synthesis methods used by other research teams had significant limitations. "When chemically synthesizing nanohybrids, researchers used ligands, which prevented nanoparticle agglomeration, on one hand, but significantly affected the charge transfer dynamics from nanoparticles to nanotubes," said Professor El Khakani. Ligands reduce photoresponse efficiency and increase the reaction timetwo effects that were not observed in nanohybrids produced by PLA since PbS is in direct atomic contact with the nanotubes' surafce.

"At the beginning, we didn't know if the nanohybrids would form in such a way as to enable their effective use for photodetection," said Ibrahima Ka, an INRS doctoral student working under the supervision of Professor El Khakani and co-supervised by Professor Dongling Ma. "By optimizing our approach, we developed nanohybrids whose photoactivity can be almost tailored at will." By integrating the new nanohybrid material into functional photoc
