Nonlinear absorption and optical limiting properties of nickel molybdate carbon nanotube composites

    The nickel molybdate carbon nanotube composites (NiMoO4/CNTs) were synthesized by solution blending method. The NiMoO4/CNTs were characterized by scanning electron microscopy (SEM), Raman spectroscopy and UV–Vis absorption spectroscopy. The (NiMoO4/CNTs)/PMMA organic glasses were obtained by dispersing NiMoO4/CNTs in methyl methacrylate (MMA) and polymerizing in a water bath at 75°C for 1h. The nonlinear optical (NLO) properties were measured via Z-scan technique. By testing we obtained that (NiMoO4/CNTs)/PMMA has a reverse saturation absorption (RSA) effect and optical limiting (OL) performance. In addition, the RSA effect is enhanced compared to other similar materials. The OL threshold (Fth) and the normalized transmittance clamping value (Tc) are calculated and fitted to be 0.83Jcm2 and 0.48Jcm2, respectively. Consequently, NiMoO4/CNTs have significant research value in the direction of extending new materials for laser protection.
