View full text Add to dashboard Cite

One-dimensional (1D) ZnO nanostructures have been studied intensively and extensively over the last decade not only for their remarkable chemical and physical properties, but also for their current and future diverse technological applications. This article gives a comprehensive overview of the progress that has been made within the context of 1D ZnO nanostructures synthesized via wet chemical methods. We will cover the synthetic methodologies and corresponding growth mechanisms, different structures, doping and alloying, positioncontrolled growth on substrates, and finally, their functional properties as catalysts, hydrophobic surfaces, sensors, and in nanoelectronic, optical, optoelectronic, and energy harvesting devices.

“…For example, the reports for SHG responses from the GaAs nanoneedles grown by the chemical vapor deposition method [9], the nanocups deposited Au by electron-beam evaporation on to silica nanoparticles [10], the ZnO nanorods grown on glass substrates by means of the low-temperature chemical bath method [11], the Pt nanowires created by the physical vapor deposition method [12], and the Au nanoholes fabricated by the focused ion beam method [13] attracted most researchers. These SHG processes are used in a wide range of applications, such as developing devices for optical processing [14], nonlinear imaging [4], and phase-sensitive amplification [15]. Because nonlinear processes through photon–photon interactions are intrinsically weak, studies on enhancement of nonlinear efficiency are crucial [16].…”

In this review, the authors study their creation of nano/micro-hierarchical structures on Ag and Ni substrates by femtosecond laser treatment and their investigation of their optical second-harmonic generation (SHG) signal intensities by SHG spectroscopy. The authors obtained the nanostructure-covered microgroove and microcube structures. These hierarchical surface structures were found to modify significantly the optical nonlinearity of the metal surfaces. The macroscopic symmetry of the surface’s shapes influenced SHG, and the excitation of surface plasmons enhanced SHG. On the other hand, the nanostructures on the microstructures had an additional effect on the generated SHG. For the microcube structures, the additional SHG emission was suppressed by removing a large amount of nanostructures. Left SHG was discussed by the effect of the propagating delay.

“…By investigating the dependence of the SH intensities on the excitation polarizations, the secondorder nonlinear susceptibility of a single CdS nanowire can be determined [20][21][22][23][24][25] . The generated SH waves from such nanowires can be analyzed by using near-field scanning optical microscopy [26] or far-field microscopic imaging [27] . Both methods are based on the detection of the back-reflected SH signal.…”

We experimentally investigate the resonant and nonresonant second-harmonic generation in a single cadmium sulfide (CdS) nanowire. The second-order susceptibility tensor is determined by analyzing the forward secondharmonic signals of the CdS nanowire. Our results show that (1) d 33 ∕d 31 ¼ −2.5 at a nonresonant input wavelength of 1050 nm; (2) d 33 ∕d 31 ¼ −1.9 at a resonant wavelength of 740 nm. The difference can be attributed to the polarization-dependent resonance.OCIS codes: 190.2620, 190.4720. doi: 10.3788/COL201715.061901.Cadmium sulfide (CdS) nanocrystals have been attracting considerable attention due to its excellent optical and electronic properties. It is a member of wide direct band gap (∼2.4 eV) semiconducting compounds and possesses large optical nonlinearities, which make it extensively useful in linear and nonlinear optoelectronic devices. In the past several years, many researchers have synthesized different CdS nanostructures, such as nanoparticles, nanoribbons, and nanowires through various growth methods [1][2][3][4][5][6][7][8] . The optical properties of such CdS nanostructures, including photoluminescence, absorption, and lasing, have been well studied [4][5][6][7][8][9][10][11][12] . Benefiting from their large second-order nonlinear response, CdS nanowires have been proven to be very useful in efficiently realizing nonlinear optical effects, such as optical correlation [13] and nonlinear optical mixing [14] . Also, the optical limiting properties of CdS nanowires were reported recently [15] . However, the secondorder nonlinear susceptibilities of a single CdS nanowire have not been well investigated.Second-harmonic (SH) generation arises from the second-order nonlinear polarization in a nonlinear optical crystal [16][17][18][19] . By investigating the dependence of the SH intensities on the excitation polarizations, the secondorder nonlinear susceptibility of a single CdS nanowire can be determined [20][21][22][23][24][25] . The generated SH waves from such nanowires can be analyzed by using near-field scanning optical microscopy [26] or far-field microscopic imaging [27] . Both methods are based on the detection of the back-reflected SH signal. Compared to the forward SH emission, the back-irradiated SH emission has a much shorter coherence length and a much lower intensity, which will reduce the quality of the SH signals and the measurement accuracy. In this work, we utilize a forward SH scattering method [28,29] , which is ideal for characterizing nanostructures with similar sizes to the wavelengths involved, to characterize the second-order susceptibility tensors of single CdS nanowires. In addition, it has been reported that the second-order nonlinear optical response of a nanowire can be significantly influenced by the resonant excitation (i.e., the SH photon energy is above the bandgap of the semiconductor nanowire) [30,31]
