The flexible organic light-emitting cell (LEC) was prepared in ambient air by using the all solution method.The material modification of the electrode layer poly (3, 4-ethylenedioxythiophene)-polystyrene sulfonic acid (PEDOT∶PSS) was carried out through the synergistic interaction of ethylene glycol (EG) doping and formic acid post-treatment.The square resistance, light transmittance and film forming effect of the thin films under different EG content and HCOOH treatment times were studied, and the influence of different cations K+, Li+ and ion content on ionic conductivity and photoelectric properties of electrolyte of the light-emitting layer was further explored.The results showed that with the increase of EG content and HCOOH treatment times, the light transmittances were improved and the square resistance of the film was reduced.When EG content was 9% and HCOOH treated twice, the film showed the best performance, the light transmittances reached 94.84%, and the square resistance of the film was reduced from 1034 Ω/sq to 84 Ω/sq.Compared with the mixture containing Li+, the mixture containing K+ (SY∶PEO∶K+) at a ratio of 1∶0.3∶0.03 showed the best ionic conductivity, which reached up to 1.343×10-4 S/cm, and the luminescent devices have favorable emission characteristics.
