摘要：
Spectral imaging for electroluminescence (EL) characterization of a light-emitting diode based on blends of poly [2,7-(9,9-di-n-octylfluorene)] (PFO) and poly [2,7-(9,9-di-n-octylfluorene)-alt-(1,4-phenylene-((4-sec-butylphenyl)amino)-1,4-phenylene)] (TFB) was performed using a two-dimensional microspectroscopy imaging system. We found that EL spectral images changed markedly with increasing applied voltage. Such a variation is presumed to have originated from the transfer of emission sites in the polymer blend layer.
