Nonlinear optical absorption studies of CoMoO4 hybrid nanostructures

The present work aims at the synthesis of CoMoO4 hybrid nanorods by hydrothermal method. The optical and structural properties of the synthesized nanorods have been characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and Scanning electron microscopy (SEM). Nonlinear optical studies of the samples were measured by single-beam open aperture Z-scan technique using 5 ns laser pulses at 532 nm. The measured optical nonlinearity of the nanorods shows a typical third order nonlinear optical behaviour including two-photon absorption (2 PA) and reverse saturable absorption (RSA). Experimental findings show that the presence of RSA in these nanoparticles makes them a promising candidate for the fabrication of optical limiting devices.
