Excited-State Dynamics and Laser Action in Epitaxial Organic Nanofibers

Abstract

We present a review on the excited-state dynamics and nonlinear optical properties of para-sexiphenyl epitaxial nanofibers grown on muscovite mica and exhibiting amplified spontaneous emission and random lasing at low photoexcitation fluences. We also report on recent advances made with alternated epitaxy of para-sexiphenyl and sexithiophene.
