Figure 6From: Water-Driven Assembly of Laser Ablation-Induced Au Condensates as Mesomorphic Nano- and Micro-TubesVibrational spectrum of the deposit of Au microtubes on vitrous silica. a b Raman shift of vitreous silica without and with the deposit of the as-formed Au condensates (blue trace) and subsequently assembled Au microtubes (red trace, the same material as in Fig. 4), respectively, showing surface-enhanced Raman scattering of D1 and D2 modes (cf. text), and minor unidentified bands, c FTIR spectrum showing OH− stretching vibration near 3432 cm−1[22]Back to article page
