| 摘 要： | 本文对以聚(2,5-二丁氧基对苯乙炔)为发光层的聚合物电致发光二极管的电致发光性能和影响其性能的因素进行了研究。其发光峰值波长为590um,起亮电压为12V,最大亮度可达112cd/m2.热处理温度和时间影响其发光强度和峰值波长,一般以200℃,真空处理3.5h为宜。还原气氛(N2+H2)下的热处理有利于电致发光性能的提高。器件在空气中具有一定的使用寿命。其量子效率可达0.16%光子/电子。并研究了器件制备工艺对性能的影响,初步探讨了聚合物电致发光机理。

| Abstract: | The electroluminescent properties of polymeric electroluminescent diodes(PELED)b.ased on poly(2,5-dibutoxy phenelene vinylene),PDBOPV,and factors effecting the properties were studied in this paper. The peak wavelength of diodes was 590urn,turn on voltage 12V,and maximum brightness 112 cd/m2.Conversion conditions of PDBOPV affected the light intensity and peak wavelength.The diodes could work in air with good stability,and quantum efficiency reached to 0.16% phototron/electron.The mechanism of electroltlminescence was investigated preliminarily also. |
