一种基于PFO掺杂的理想白光有机电致发光器件
白光电致发光 PFO MEH-PPV掺杂 色坐标稳定性
2012/4/12
研究了以芴类蓝光材料PFO为主体，通过掺杂MEH-PPV得到单层的白光有机电致发光器件，并从掺杂浓度对器件的光谱特性和色坐标稳定性的影响方面对其发光性能进行了分析研究。在MEH-PPV以2.5 Wt%掺杂时，器件开启电压为3 V，发光色坐标可达到标准白光等能点(0.33, 0.33)，器件发光色坐标在5～20 V很宽的范围内随电压变化幅度很小，基本稳定在白光区。

新型共轭聚合物PFO-BT15发光二极管的电老化研究
共轭聚合物 电老化 电致发光 喇曼光谱
2009/4/24
PFO-BT15是一种电致发光中心波长为550 nm的新型共轭高分子聚合物材料，将其制成发光二极管器件，结构为ITO玻璃/聚合物PEDOT(120 nm)/有机聚合物PFO-BT15(80 nm)/Ba(4 nm)/Al(200 nm)，用环氧树脂对阴极侧进行了封装，以减少氧气和水分的进入，从而影响器件的发光性能。在室温环境下对同样的器件进行不同电流密度的电老化处理，记录器件的电流电压曲线，再对老...
