Surface-enhanced Raman scattering on organic-inorganic hybrid perovskites

Surface-enhanced Raman scattering (SERS) on organic-inorganic hybrid perovskites is explored and for the first time the SERS activity (EF >= 10(4)) 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.
