We have fabricated a uniform TiO 2 thin film on a silica microsphere by using the so-called sol–gel reaction. Characterization of the TiO 2 thin film was carried out by scanning electron microscopy, Raman scattering, and the attenuated-total-reflection (ATR) method. We have observed optical ...
(Fig.8). The Raman scattering peaks for ethanol are also shown in the figures, and the peak at 884 cm−1was used for the normalization of the intensities of different SERS spectra. The colloidal Au-SiO2-mp2 detected CV in the order of 10–8 M (Fig.8a). We calculated the ...
, 2003). Surface-enhanced Raman scattering could provide a specific labeling probe when dyes such as Texas Red are doped on nanoparticles, with Raman and fluorescent detection (Santra et al., 2001a; Lim et al., 2006). As a representative example of Raman tags for multiplexing, six dyes ...
silica microspheresilver nanostructurelaser irradiationThe high enhancement factor (EF) of surface-enhanced Raman (SERS) probes is an important parameter for high-sensitivity Raman scattering measurement applied to environment control. In this article, we present a SERS probe based on silver nano-...
We demonstrate experimentally a silica microresonator-based single-mode Raman laser tunable in the U-band and beyond. The Stokes wavelength is tuned in the 1631-1685 nm range when tuning a C-band pump laser in the 1520-1570 nm range. We also demonstrate switching between Raman lasing modes ...
surface enhanced Raman scattering/ silica-coated gold nanorod synthesisThe applications of colloidal gold nanorods (AuNRs) as substrate for surface-enhanced Raman scattering (SERS) inevitably have to deal with a bilayer of cetyltrimethylammonium bromide (CTAB) around the AuNR surface. Here, we report...
