Non-linear optical effects (SRS) in nanostructured polyaniline LED

Author affiliations

Abstract

Non-linear optical effects (the stimulated anti-Stokes Raman scattering, SRS) have been observed in a nano-structured polyaniline LED. The mechanism of the anomalous enhancement is based on changes of the Raman cross section due to the resonant interaction involving stretching vibrations of triple bonds – diacetylene units, formed under strong excitation conditions in degradated polyaniline molecules, which are highly efficient in normal Raman scattering and SRS active. This is the first observation of SRS in a conducting polymer LED.
