Abstract

Sensitive surface-enhanced Raman scattering active substrate based on gap surface plasmon polaritons

Ordered Nanocap Array Composed of SiO2-Isolated Ag Islands as SERS Platform

“…A N is the half surface area of one PS with diameter 200 nm, and σ is the surface area occupied by a single PATP adsorbed on the substrate value, which is estimated to be 0.20 nm 2 . 49,50 N bulk and N SERS can be calculated to be 8.46 × 10 10 and 1.54 × 10 6 , respectively. I SERS /I bulk (Figure 7 and Supporting Information, Figure 4…”

Controllable Charge Transfer in Ag-TiO2 Composite Structure for SERS Application

“…The SERS enhancement factor (EF) is calculated from 10 randomly selected points for the TiO 2 (10 nm)/Ag (10 nm) bilayer and TiO 2 -Ag (20 nm) co-sputtered monolayer according to the equation [ 38 , 39 , 40 ] ( Figure 7 ), , where and are the SERS intensity of the bands at 1440 cm −1 assigned to PATP absorbed on TiO 2 /Ag arrays and the Raman intensity of the band at 1403 cm −1 assigned to the solid PATP, respectively. is the average number of molecules in the scattering volume (V) for the Raman (non-SERS) measurement.…”

Nanocap array of Au:Ag composite for surface-enhanced Raman scattering

“…The enhancement factors (EFs) for PATP and R6G is calculated according to the equation EF = (I SERS  N bulk )/(I bulk  N ads) , where I SERS and I bulk are the SERS intensity of the bands at 1072 cm À1 for PATP absorbed on Au:Ag arrays and the Raman intensity of the band at 1090 cm À1 for the solid PATP, respectively (Supporting information) [37,38]. The average number of molecules in the scattering volume (V) for the Raman (non-SERS) measurement is N bulk = C RS VN A .…”
