Electroreflection spectra have been measured to investigate the electric field effects on excitonic modulation for several subbands in a ZnSe–Zn 0.8 Cd 0.2 Se superlattice structure. In photoluminescence spectra, three subbands originating from the

Time-resolved difference absorption spectra of polycrystalline thin films of C 60 were measured by femtosecond pump–probe spectroscopy. The decay dynamics of the excited state can be explained in terms of a model of localized excitations. Self-trap

Femtosecond transient absorption of a poly(3-dodecylthiophene) film is measured in a wide spectral range from visible to near-infrared. Our results show that the transient absorption consists of four decay components. The two faster components are as
