聚(对-苯撑乙烯)衍生物蓝色发光二极管及平面显示

成功地合成了柔性脂肪链段和刚性发光链段相互交替的共聚物,并对其进行了表征.发现该聚合物的荧光随柔性链段的增长而增强的实验结果.用所合成的共聚物作发光层,研制出了发光亮度可达190cd/m~2,最小开启电压为15V的发蓝色光的聚合物发光二极管及平板显示屏.讨论了(口恶)二唑衍生物(PBD)和8-羟基喹淋铝(Alq_3)电子输运层的引入对器件的发光亮度和稳定性的影响.     

Bright red electroluminescent devices based on a soluble lanthanide complex Eu(DBM)_3(phen)

Electroluminescent devices with PVK film doped with Eu(DBM)3(phen) and PBD were fabricated. The device structure of glass substrate/indium-tin-oxide/PPV/PVK:Eu(DBM)3-(phen):PBD/Alq3/Al was employed. The emissive layer was formed by spin-casting method. A sharply red electroluminescence with a maximum luminance of 114.4 cd/m2 was achieved at 42 V.
