Descriptions

his is the experimental dataset used in the paper Applied Surface Science, 662: 160107 (2024) (https://doi.org/10.1016/j.apsusc.2024.160107) in which a novel Surface-Enhanced Raman Spectroscopy (SERS) sensor based on a nanostructured substrate, calcium silicate hydrate (C-S-H), the main hydration product of Portland cement, was synthetized. The procedure involves first the incorporation of silver within the nanostructure of the gel (C-S-Ag-H) and second the modification of the surface of pellets of the newly synthesized material by laser irradiation at 532 nm or 355 nm. This data set includes the results of the effect of silver on the gel structure via visible UV spectroscopy, micro-Raman and 29Si Magic Angle Spinning Nuclear Magnetic Resonance (MAS NMR). It also includes the characterization analyses of the C-S-Ag-H pellets by X-ray Photoelectron Spectroscopy (XPS) to determine the silver oxidation state and the assessment of their SERS activity before and after laser irradiation using for the latter Rhodamine B (RhB) as a probe.
