Abstract
Photoluminescence (PL) based on Förster energy transfer between p-sexiphenyl (p-6P) and 5,5â²-bis(4-phenylyl)-2,2â²-bithiophene (BP2T) was investigated for their coevaporated and laminated thin films. In the former films, fluorescence quenching of the p-6P was accompanied by appearance of BP2T fluorescence, which indicated existence of the energy transfer between the donors and the acceptors. The latter films were fabricated by successive depositions of p-6P, MgF2 and BP2T in which the thickness of the MgF2 spacer was varied. The energy-transferred acceptor fluorescence was suppressed by the spacer thicker than the Förster distance (â¼10Â nm).
