✦ Synopsis

A carbon nanotube (CNT) thin film prepared by the thermal CVD method was flashed by second harmonic light of a pulsed Nd:YAG laser (Ξ» = 532 nm) under various laser fluences. A part of the defective CNTs and amorphous carbon in the film was removed by 10 shots of laser irradiation at E f = 600 mJ/cm2. Raman spectra of the laser irradiated CNT thin film showed the increase of I G /I D ratio, which indicated that the CNTs thin film was purified by laser irradiation. A multi-walled CNTs (MWCNTs) based gas sensor treated by laser irradiation showed good sensor response to NO gas.

A comparative study was made of sorted semi-conducting single walled carbon nanotube (SWCNT) films and unsorted SWCNT films for gas sensing applications. The transmission line method is used to monitor separately the SWCNTs film resistance and the contact resistance between electrodes and the SWCNTs
