“…The characteristic emission peaks of Tb 3 + ion can be observed in the emission spectra when the excitation wavelength is 291 nm (Figure 5b), and the emission peaks respectively belong to the energy level transitions of 5 D 4 ! 7 F 6 (492 nm), 5 Figure 6b respectively exhibit the excitation spectrum and emission spectrum of L-SJAF with various contents of PANI (10, 25, 40 and 60%) monitored by 548 nm and excited by 291 nm UV light. The intensities of excitation light and emission light of L-SJAF show the same trend, viz., the luminescent intensity decrease with the increase of PANI content.…”

“…With the continuous demand for integrated and portable nanodevices, functional materials with single-performance and large-size are gradually unable to meet the developing requirements of devices, and thus the realization of multiple properties in one material has been widely concerned by researchers, and the material with multiple properties has wide applications in many fields [1][2][3][4] Anisotropic materials can obtain different functions in different direction , [5,6] Anisotropic conductive film (ACF) has been used in many fields on account of their copacetic mechanical capacity, high electrical conductivity [7][8][9] and environmental pollution-free, [10] such as, storage battery [11,12] wearable pressure sensors, [13] filtration separation, [14] transparency electrode materials, [15] etc. ACF is classified into different types.…”

Manipulation of a Single Metal Nanowire by an Unpolarized Gaussian Beam

“…Plasmonic metal nanowires are known as promising components in nanooptical systems because of their fascinating ability for concentrating and guiding light in subwavelength volumes. − The accurate manipulation of metal nanowires is highly desired because the plasmonic responses are sensitive to their orientation and position. − An optical-force-based manipulation technique, optical tweezers, has attracted great attention for its noncontact, low-damage, and high-precision properties. − In general, two optical forces acting on the particles are involved: the scattering force, which pushes the particles along the light propagation direction, and the gradient force, which attracts the particles toward the focus. The particles can be trapped near the light focus when the gradient force exceeds the optical scattering force. , Conventional optical tweezers with a tightly focused Gaussian beam have been used to trap and manipulate various particles including semiconductor nanowires, − metal nanoparticles, and biological cells. , However, for metal nanowires, the scattering force dominates over the attractive gradient force because of its strong absorption and scattering features, and stable capture is unattainable in a single Gaussian beam. , Various approaches have been proposed in terms of either enhancing the gradient force or reducing the scattering force.…”

Dynamic Orientation of Silver Nanowires via Photoalignment for Liquid Crystal Display Technology

“…Mesoscale nanoparticles have been studied by experts in the fields of chemistry, physics, electronics, mechanics, and biology. − Common materials are functionalized to obtain new macroscopic properties. − Anisotropic silver nanowires (AgNWs) with large, controllable aspect ratios find applications in optics and electronics because their one-dimensional (1D) characteristics facilitate the fabrication of flexible transparent electrodes, polarized light-based devices, antennas, surface-enhanced Raman scattering (SERS) platforms, biomimetic actuators, and nanocomputers . AgNWs have been assembled via stretching, flow alignment, electric fields, water–air and oil–water–air interfaces, , the Langmuir–Blodgett method, external pressure application, and several coating methods. , However, the fabrication and manipulation of tunable microdomain AgNWs remains challenging.…”
