摘　　要：用夹在两层SiO2 之间的发光聚合物C9 PPV作成器件 ,在交流电激发下得到了超出有机电致发光黄绿色发光的蓝色发光 .通过对器件光学特性的研究 ,发现这种发光源于SiO2 中加速电子直接碰撞激发有机发光层而引起的类阴极射线发光 .使用非对称结构 。We have prepared a device of C 9 PPV sandwiched between two SiO 2 layers and obtained the blue light in addition to the yellow green emission under ac electric field excitation. By studying the optical characteristics of the device, we found that the emission was induced by direct bombardment of the accelerated electrons from SiO 2. This emission is termed by us as cathodo luminescence like emission. By using unsymmetrical structure, we realized mutual enhancement of cathodo luminescence like and Organic electroluminescence.
