Analysis of the excited-state absorption spectral bandshape of oligofluorenes
(2010)We present ultrafast transient absorption spectra of two oligofluorene derivatives in dilute solution. These spectra display a photoinduced absorption band with clear vibronic structure, which we analyze rigorously using ...

Optical properties of conjugated poly(3-hexylthiophene)/ [6,6] -phenyl C61 -butyric acid methyl ester composites
(2007)In this work, we present the evolution of optical constants as a function of [6,6] -phenyl C61 -butyric acid methyl ester (PCBM) concentration for conjugated poly(3-hexylthiophene)/ [6,6] -phenyl C61 -butyric acid methyl ...
