Abstract
The nickel molybdate (NiMoO4) flakes were synthesized by a hydrothermal method. The scanning electron microscopy (SEM) images show that NiMoO4 holds an irregular flake structure. The energy dispersive spectrometer (EDS) results indicate that the O, Ni and Mo elements are uniformly distributed of NiMoO4. Then an appropriate amount of NiMoO4 was dispersed in methyl methacrylate (MMA), and polymerized at 75 ℃ for 45–60 min to obtain NiMoO4/PMMA organic glasses. The nonlinear absorption (NLA) properties were investigated by an open-aperture (OA) Z-scan technique. The NiMoO4/PMMA organic glasses exhibit a typical saturable absorption (SA) effect at the radiation wavelength of 532 nm. The mechanism of SA effect is related to the unique flake structure of NiMoO4, the band gap (Eg) of NiMoO4 and the thermo-optic effect. The results indicate that NiMoO4 flakes can be widely applied in Q-switched and mode-locked lasers.
