Experimental measurements of Mo6S4.5I4.5 nanowires investigating nonlinear optical extinction (NLE) of nanosecond laser pulses are reported. The experiments were performed using the open aperture Z-scan technique at 532 nm and 1064 nm. Concentration dependent studies were performed for Mo6S4.5I4.5 nanowires dispersed in isopropanol at 0.1, 0.05, 0.025 and 0.0125 g/l, showing direct correlation between the NLE response and nanowire bundle diameter. Further to this, intensity dependent scattering experiments are reported for Mo6S4.5I4.5 nanowires dispersions at wavelengths of 532 nm and 1064 nm. Mechanistic implications of the optical extinction are discussed. The NLE was compared with that for a stabilized multi-walled carbon nanotube (MWNT)-polymer composite dispersion.
