Thin films made of a low-band gap copolymer poly{4,6-bis(3-dodecylthien-2-yl)thieno[3,4-c][1,2,5]thiadiazole-alt-9,9-bis(2-ethylhexyl)-fluorene} (CDTF) and made of its blends with soluble fullerene derivative [6,6]-phenyl C61-butyric acid methyl ester (PCBM60) with various ratios were studied by means of UV–vis absorption spectroscopy and Raman microspectroscopy. It was found that inhomogeneities which are present in thin films consist of higher content of PCBM60 than the rest of the film. Photoluminescence of both components observed in the Raman spectra was distinguished using two different excitation wavelengths.
