Magnetic Nanorods for Optofluidic Applications
نویسندگان
چکیده
We have developed a method for laser beam manipulation by using a colloid of nickel nanorods produced by electroplating chemistry. It is shown that the shape of the laser beam passing through a colloid of nickel nanorods can be altered by varying the applied magnetic field. This effect is caused by multiple scattering and diffraction of the laser beam by the nanorods. Compared with spherical nanoparticles, magnetic nanorods are better suited for illumination applications because they are stable in a rotating magnetic field. By rotating the diffraction pattern, one can illuminate a large area.

In this work, Co3O4 nanorods were successfully prepared by microwave-assisted solid state decomposition of rod-like CoC2O4.2H2O precursor within a very short reaction time (6 min) without the use of a solvent/surfactant and complicated equipment. The as-obtained Co3O4 nanorods were fully characterized by X-ray diffract...
متن کاملAll-optical tuning of a magnetic-fluid-filled optofluidic ring resonator.
An all-optical tunable optofluidic ring resonator (OFRR) is proposed and experimentally demonstrated. The all-optical control of a silica microresonator is highly attractive, but it is difficult to realize because of the relatively weak Kerr effect and the absence of a plasma dispersion effect of silica. Here, we infuse a silica microcapillary-based optofluidic ring resonator with a magnetic fl...
