Novel MnMoO4 nanofibers: preparation, microstructure analysis and optical properties

In the present research, the electrospinning technique was used successfully to fabricate MnMoO4 nanofibers. The as-electrospun fibers were calcinated at 400 A degrees C for 2 h. The fibrous webs of MnMoO4 were characterized by X-ray diffraction (XRD) measurement, scanning electron microscopy (SEM), Fourier-transform-infrared spectroscopy, and Z-scan technique. XRD analysis of MnMoO4 nanofibers was presented by the Williamson-Hall method. The results indicate that the average diameters of the calcinated fibers obtained from the SEM analysis were about 100 +/- 10 and 120 +/- 20 nm when feed rates of the solution in electospining were 0.5 and 1 ml/h, respectively. The nonlinear optical behavior of viscous sol of MnMoO4 has been observed using both open and closed aperture Z-Scan technique at 534 nm. The results related to the nonlinear optical behavior indicate that the MnMoO4 nanofibers may have potential nonlinear optical properties.
