Surface-enhanced Raman scattering on organic–inorganic hybrid perovskites

Abstract

Surface-enhanced Raman scattering (SERS) on organic–inorganic hybrid perovskites is explored and for the first time the SERS activity (EF ≥ 10⁴) of the nanostructured CH₃NH₃PbBr₃ has been proved. Here, the SERS profile displays high similarity with the normal Raman spectra and the enhancement mechanism is discussed according to the charge transfer contribution.
