Uniform Layer

The LSPR of Au nanospheres shows almost no shift in the extinction spectrum with attachment of a silica domain but considerable shift with a uniform layer of silica, indicating LSPR can be used to differentiate the segregated/uniform dielectric distribution.

Hcl Solution

In HCl solution, the Se (IV) was reduced to SeH2 by NaBH4, and absorbed by solution of ethanol-AgNO3. The Ag+ was reduced to nanosilver that exhibited surface plasmon resonance absorption (SPR) peaks at 292 nm and 420 nm. Under the selected conditions, the value at 292 nm was linear to the concentration of Se (IV) in the range of 0.08-2.0 μg/mL, a detection limit of 0.04 μg/mL. The proposed method was applied to detect Se (IV) in water samples, with satisfactory results.
