Raman scattering is characterized by the inherently weak inelastic scattering of photons, influenced by molecular vibrations or rotations. Recent advances have shifted from traditional electromagnetic enhancement methods to chemically enhanced Raman scattering, offering significant advantages. However, these advancements have typically depended on indirect and empirical models.

Employing this method, this work has developed a series of rationally designed Raman enhancers made from conducting polymers (CPs), such as poly(3,4-ethylenedioxythiophene) (PEDOT), with optimized morphological traits and compositions. These enhancers significantly improve surface-enhanced Raman spectroscopy (SERS), achieving a reproducible enhancement factor of up to 106, and boost Raman lasing, with a remarkable 40-fold increase in energy conversion efficiency.
