Large-area and uniform amorphous metallic nanowire arrays prepared by die nanoimprinting

Highly Uniform and Reproducible Surface Enhanced Raman Scattering on Air-stable Metallic Glassy Nanowire Array

“…The laser beam power was 4.7 mW and the laser beam diameter was 5 μm. Excitation wavelength of 514 nm (according to the previous literature21), scan time of 30 s, field lens of 20 times and accumulation of 4 times were applied. The SERS mapping measurements were carried out in the center of the droplet by a microscopic confocal Raman spectrometer (LabRAM HR Evolution, HORIBA Jobin Yvon, France) using a charge-coupled device (CCD) detector with a resolution of 0.65 cm −1 .…”

“…Very recently, it was reported that with inexpensive templates such as anodic aluminum oxide (AAO), metallic glassy nanowire arrays (MGNWAs) can be prepared by nanoimprinting technique18192021, which is a rapid, controllable, green and one-step forming technology. What's more, MGNWAs possess better mechanical properties as well as corrosion resistance than their crystal counterparts2022, making them easy to be conserved and durable in application.…”

“…Then it is possible to employ the MGNWAs for SERS detection. Pd 40.5 Ni 40.5 P 19 2123 is a classic MG composition and possesses wide supercooled liquid region (SCLR) as well as excellent anti-oxidation properties, which endows it excellent thermoplastic forming ability. What's more, Pd and Ni possess stable SERS activity when excited by different wavelengths of light24.…”

High thermal stability of the amorphous oxide in Ti44.5Cu44.5Zr7Be4 metallic glass

“…[11][12][13] Based on such exotic properties, it has been reported that metallic glasses can be used as functional materials for binding 14 and nano/micro imprinting. 15 As a result, metallic glasses have been successfully applied for electrode for solar cell 16 and catalyst for fuel cell. 10,[17][18][19] One of the prerequisites for such applications is that metallic glasses should have a wider SCL region, which can provide a larger processing window for fabrication.…”
