Abstract
We have prepared a device of C9-PPV sandwiched between two SiO2 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 SiO2. 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.
