STUDIES ON THE ELECTROLUMINESCENT PROPERTIES OF POLY(2,5-DIBUTOXY PHENELENE VINYLENE)

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．

he 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/m'.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.
