Surface enhanced Raman scattering of adsorbates on Au–CsPbIBr₂ perovskite-based nanocomposites: charge-transfer and electromagnetic enhancement

Abstract

A simple composite SERS substrate Au–CsPbIBr2 was prepared and its synergistic mechanism and influencing factors were discussed.

Fabrication of Ag-perovskite substrates for surface-enhanced Raman scattering via all-vacuum deposition

“…As a result, any background noise arising from minor contaminations is negligible. Additionally, perovskite exclusively produces SERS signal through CM, 26,40 rendering its contribution to background noise insignificant. Despite the Ag-perovskite substrates offering weak EMM due to the rarity of hot spots, both the perovskite layer and silver nanoparticles contribute to SERS through CM.…”
