Abstract: A report on a hybrid system of ZnO nanoparticles on multiwalled carbon nanotube (MWNT) scaffolds synthesized for ultrafast nonlinear optical switching, is presented. Resonant micro-Raman Spectroscopy and photoluminescence spectroscopy using He-Cd laser under back-scattering geometry is employed to characterize the as-grown ZnO-beaded MWNTs. The large and ultrafast saturable absorption in ZnO-beaded MWNTs suggests that the samples can be used as saturable absorber devices. Combining the three-photon absorption properties of ZnO with the satiable absorption properties of CNTs to yield ZnO/MWNTs hybrid materials would also find important applications in future multifunctional nanodevices.
