摘要：

We measured the 785-nm excited Raman spectrum of a pentacene:C-60 blend film. The 1462-, 492-, and 268-cm(-1) bands of C-60 showed broadening in bandwidth and downward shifts in peak wavenumbers, whereas such broadening and downward shifts were not observed for pentacene. These results indicate that there are pentacene crystallites among the amorphous C-60. The intensity ratio of the 1598-cm(-1) (B-3g) and the 1534-cm(-1) (A(g)) bands indicates that pentacene molecules have standing orientations. The appearance of a 514-cm (1) band (Flu) and the splitting of the H-g bands of C-60 indicate symmetry lowering induced by the interaction between pentacene and C-60 molecules. (C) 2015 Elsevier B.V.
