【摘要】 采用聚苯胺作阳极，ＭＥＨ－ＰＰＶ作发光材料，我们合成了有机高分子发光二极管器件．通过对聚苯胺的掺杂，发现器件的发光强度比未掺杂器件提高３０％，起始工作电压降低２５％．寿命测量还显示以聚苯胺或掺杂聚苯胺作电极的二极管器件，在给定电压下的工作寿命要比直接用导电玻璃作电极的二极管器件提高７～１０倍以上．更多还原

【Abstract】 Abstract Polyaniline and doped polyaniline is employed as positive electrode to fabricate organic polymer MEH PPV light emitting diodes (LEDs). It is found that the intensity of the light emitting of the doped devices is enhanced by 30% and the turn on voltage is lowered by 25%. The measurements of the lifetime show that LEDs with polyaniline and doped polyaniline as electrodes can work ten times longer than the usual LEDs with ITO as electrodes directly.更多还原
