摘要：
We report on the considerable increase of electroluminescent (EL) intensity in planar organic light-emitting diode structures based on semiconducting polymer PFO and ZnO nanoparticles composite films operated by alternating-current (AC) voltages with respect to that operated by direct current. It was established that an increase of frequency from 0 to similar to 30 kHz results in increase of EL intensity of such structures by a factor of 30. The EL emission takes place at positive AC bias and the EL spectral range is the same as that for the photoluminescent emission spectrum for the same sample. It was shown that applying AC voltage is effective tool in producing strong EL emission in planar composite light-emitting structures. (C) 2015 Elsevier Ltd. All rights reserved,
