Surface-enhanced Raman scattering activities and recyclability of Ag-incorporated WO3 nanofiber-based substrates

Ammonium ion pre-intercalation stabilized tunnel h-WO3 for fast NH4+ storage

“…S3 †) of (NH 4 ) x WO 3 shows peaks at 277.7, 771.4, 917.3, and 957.7 cm À1 , which are characteristic of h-WO 3 . 35 The Raman (Fig. S3 †) bands at 340.3, 675.6, 807.2, and 950.7 cm À1 stand for WO 3 $0.33(H 2 O).…”

LSCF–WO3 semiconductor composite electrolytes for low-temperature solid oxide fuel cells

“…The peaks at 268 cm −1 and 808 cm −1 were attributed to the tensile vibration of W-O-W bond and the bending vibration of W]O bond, respectively. [36][37][38] The peaks centered at 546 cm −1 and at 632 cm −1 were ascribed to LSCF. 33,39 The sharp peak at the 1088 cm −1 position indicated the formation of Li 2 CO 3 in the electrolyte layer.…”

Recent Development of Polymer Nanofibers in the Field of Optical Sensing

“…They utilized the surface plasmon resonance and SERS effects of metal nanoparticles to amplify the signal of the target ions. (3) For dye detection, Chen et al [105], Chen et al [106], Juntaracena et al [107], Nasr et al [108], Sang et al [109], Wan et al [110], and Zhao et al [111] used nanofibers decorated with metal nanoparticles or metal oxides to detect various dyes, such as Rhodamine 6G, Sudan I, Crystal Violet, Methylene Blue, etc. They employed the SERS effect of the nanofiber substrates to achieve high sensitivity and specificity for dye detection.…”
