At high forward bias, the current–voltage characteristic is space charge limited. At low forward bias, it follows an exponential law. Whereas the electroluminescence (EL) in devices with non-fluorinated indium–tin oxide electrodes degrades in few minutes, EL intensity in devices with FTO electrodes shows little degradation after 1300 min of operation. This result indicates that the well known beneficial effects of fluorinated species in the improvement of resistance to irradiation and carrier injection degradation in metal–oxide–semiconductor devices might be also observed in PS devices.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2012-05-30T17:29:06Z No. of bitstreams: 1 __ac.els-cdn.com_S004060...f59a4b8a28017c678978c4bd20746.pdf: 271686 bytes, checksum: 1841299c374097092889f5a7c42eadf7 (MD5)Made available in DSpace on 2012-05-30T17:29:06Z (GMT).
