摘　　要：高荧光的吩基吡啶铍(Bepp2 )作为发射层构成高效蓝色电致发光器件。这一由空穴注入层、空穴传输层、Bepp2发射层组成的多层器件,使用一电子传输层以获得高性能。这种器件结构,最大亮度达6 200cd·m-2、电致发光效率1. 3cd/A(0. 71lm/W),吩基吡啶铍(Bepp2 )的电致发光光谱峰值在451nm。这些初步的结果表明配合物铍应用于电致发光是非常有前景的材料。在化学方面的进一步考察和新的羟苯基吡啶金属配合物电致发光器件的优化也在进行中。Efficient blue light organic electroluminescent (EL) devices were fabricated by using a highly fluorescent bis(2-(2-hydroxyphenyl)-pyridine)beryllium(Bepp 2) as an emitting layer. The multiplayer devices, a Bepp 2 emitting layer, and an electron transport layer were employed in order to obtain high performance. For the devices, the maximum luminance of 6 200 cd/m 2 and electroluminascent efficiency of 1.3 cd/A (0.71 lm/W) were achieved. The EL spectrum peak of Bepp 2 appeared at 451 nm.
