“…Rhodamine 6G and riboflavin have both been used as analyte molecules in several cases to investigate the optimization of different production of SERS substrates. Furthermore, using the optimized substrates, the detection limit is determined for both analytes [4,23,33,[42][43][44][45].…”

In this study, metallic nanoislands were prepared by thermal annealing of gold thin film produced by vacuum evaporation on a glass substrate to investigate the surface-enhanced Raman scattering (SERS) effect on them. The influence of the analyte on the enhancement factor of SERS was studied with riboflavin and rhodamine 6G dye. Two laser excitation sources at 532 and 633 nm wavelengths were used for SERS measurements. We found that the enhancement factors of the gold nanoisland SERS substrates were influenced by the analytes’ adsorption tendency onto their surfaces. The SERS amplification was also found to be dependent on the electronic structure of the molecules; higher enhancement factors were obtained for rhodamine 6G with 532 nm excitation, while for riboflavin the 633 nm source performed better.

“…1B, the interplanar distance was measured to be 0.235 nm, which matched the reection from the Ag {111} crystal planes. 27 The SAED pattern (Fig. 1C) of the AgNWs exhibited bright spots corresponding to the {111}, {220}, and {311} crystal planes, indicating the polycrystallinity of the AgNWs.…”

“…As a comparison, continuous, macroscopically long, and large-area pure metal nanostructure can be prepared by the solid state ionics method in the absence of templates and subsequent purifying processes, thus making the solid state ionics method a widely employed approach to prepare various metal nanostructures [10][11][12][14][15][16][17][18]. However, at present, the microscopic mechanism of the solid state ionics method is yet to be established to fully harness the potential of such a process.…”

A macroscopic silver nanowire (AgNW) network is grown by solid state ionics method. The ion flow during growth of the AgNW network is controlled by maintaining a current in the order of 10 −7 A. Scanning electron microscopy (SEM) analysis reveals that the growth direction of AgNWs in the network is irregular and spread evenly in all directions and the nanowires are 40-160 nm in diameter. The microcosmic mechanism of silver nanostructures grown by the solid state ionics method is established by real time and in situ SEM analysis of the growth process of the AgNW networks. To study the photoelectric properties of the network, a self-supported AgNW network sample (~1 mm wide and 8 mm long) is irradiated with lasers of different wavelengths of 375, 405, 532, 633, 808, and 1064 nm and 10.6 µm, and changes in the current between the two ends of the sample are recorded. The network displays negative photoconductance effect, and the maximum light responsivity is 43 mA W −1 . The network displays light responsivity in the ultraviolet light-to-mid-infrared light region, with response times of tens of milliseconds. These findings indicate that the AgNW network has broad application prospect in ultra-wide spectrum photoelectric detection.
