“…Finally, it is worth mentioning that other Ni nanostructures have been used to coat semiconductors, leading to interesting magnetic effects. For instance, carbon nanotubes decorated with Ni nanoparticles have been applied for sensing quantum wave propagations in a variable magnetic field [ 40 ]. The advantage of Ni against carbon allotropes is their adhesive strength on substrates.…”

Nickel nanopillar arrays were electrodeposited onto silicon substrates using porous alumina membranes as a template. The characterization of the samples was done by scanning electron microscopy, X-ray diffraction, and alternating force gradient magnetometry. Ni nanostructures were directly grown on Si by galvanostatic and potentiostatic electrodeposition techniques in three remarkable charge transfer configurations. Differences in the growth mechanisms of the nanopillars were observed, depending on the deposition method. A high correlation between the height of the nanopillars and the charge synthesis was observed irrespective of the electrochemical technique. The magnetization measurements demonstrated a main dependence with the height of the nanopillars. The synthesis of Ni nanosystems with a controllable aspect ratio provides an effective way to produce well-ordered networks for wide scientific applications.

“…Most of Pt-CNT were studied as electrocatalyst [9,10] and sensor [11]. The linear optical properties of Pt-CNT in the UV-vis range have shown a plasmon resonance absorbance at 235 nm [12] and 253 nm [13], while the investigation of their NLO responses, specifically the third-order NLO properties have shown the photothermal and thermo-conductive effects of Pt-MWCNTs induced by nanosecond pulse irradiation revealed an effective phonon-photon interaction in the samples which modulated by nanosecond pulses at 532 nm wavelength [14].…”

Platinum-multiwall carbon nanotubes (Pt-MWCNTs) was prepared through a chemical reduction and was characterized by using UV–Vis Spectrophotometer, Transmission Electron Microscopy (TEM), Field Emission Scanning Electron Microscopy with Energy Dispersive X-Ray (FESEM/EDX) and Raman Spectroscopy. Through this chemical reduction, Pt ions were reduced by the addition of sodium dodecyl sulfate (SDS) and Pt was in-situ deposited on the exterior walls of MWCNTs. TEM and FESEM/EDX analyses have confirmed the presence of Pt on the surface of MWCNTs. From Raman Spectroscopy, the ID/IG of MWCNT is 0.66 while ID/IG of Pt-MWCNT is 0.71, showing that not much defects were resulted by the functionalization of Pt on the surface of MWCNT, while from UV-Vis spectra, Pt-MWCNT is found to absorb at about 265 nm due to the presence of Pt nanoparticles that caused a weak surface plasmon resonance (SPR) absorption in the UV region which will contribute to the NLR measurement. The resulted Pt-MWCNTs was then investigated its third-order nonlinearity response as suspension in water using continuous wave laser and z-scan measurement at 532 nm. Pt-MWCNT displays good transmittance profile and self-defocusing effect with excitation intensity is in order of 10-9 cm2/W. The presence of Pt on the surface of MWCNT has contributed to intrinsic properties and resulted in nonlinear refractive (NLR) effect. Thus, Pt-MWCNT is considered to possess significant third-order nonlinear responses considering its low Pt content and has potential in the development of photonics devices.

“…Moreover, hierarchical carbon nanostructures have been attractive as a platform for the fabrication of plasmonic-based sensors. The light-to-physical conversion efficiencies of CNT have been tailored to be significantly larger for specific quantum processes derived from metal decoration methods [18]. In addition, polarization and irradiance conditions can be chosen to produce multivalent effects that can be explained by simple fractional models in real applications [19].…”

A strong contrast in the third-order nonlinear optical effects exhibited by hierarchical nanostructures explored in a bidirectional optical circuit is reported. The samples were integrated by multiwall carbon nanotubes and platinum-decorated carbon nanotubes synthetized by an aerosol pyrolysis technique and followed by a chemical vapor deposition method. Coupled and decoupled third-order nonlinear optical properties of the nanocomposites were studied. A nanosecond two-wave mixing experiment at 532 nm wavelength was conducted to analyze the optical Kerr effect in the samples. Multi-photonic interactions were evaluated by a single-beam transmittance as a function of input irradiance and volume fraction of the nanoparticles integrated in the nanohybrids. A two-photon absorption process was identified as the main physical mechanism responsible for the anisotropy in the observed optical nonlinearities. Random carbon nanotube networks in film form were put on top of platinum-decorated carbon nanotubes in order to build up a bilayer sample featuring optical selectivity. The switching of optical signals in propagation through the samples was obtained by an orientation-selectable optical transmittance. Unidirectional optically controlled laser pulses dependent on irradiance and polarization in a two-wave mixing was proposed with potential nanophotonic and nanoelectronic applications. The design of signal processing functions driven by nanohybrid platforms can be contemplated.
