Abstract

The nickel molybdate carbon nanotube composites [Formula: see text] were synthesized by solution blending method. The [Formula: see text] were characterized by scanning electron microscopy (SEM), Raman spectroscopy and UV–Vis absorption spectroscopy. The [Formula: see text] organic glasses were obtained by dispersing [Formula: see text] in methyl methacrylate (MMA) and polymerizing in a water bath at 75°C for 1[Formula: see text]h. The nonlinear optical (NLO) properties were measured via [Formula: see text]-scan technique. By testing we obtained that [Formula: see text] 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 [Formula: see text] and the normalized transmittance clamping value [Formula: see text] are calculated and fitted to be [Formula: see text] and [Formula: see text], respectively. Consequently, [Formula: see text] have significant research value in the direction of extending new materials for laser protection.
