Abstract: (606 Views)
In this work, the design and fabrication of a green microcavity OLED by Al-electrode layer as a top mirror and a Distributed Bragg Reflector (DBR) bottom mirror in order to enhance quality factor(more than51) with high reflectivity and optimal electrical properties was considered.The experimental results show a substantial enhancement of the electroluminescence (EL) intensity as well as a reduction of the spectral width at a half maximum. Finally, we analysed the parameters that still limit the Q-factor, paving the way for future improvements. The proposed approach can be exploited for the fabrication of novel organic light sources for represents an important step towards the realization of organic lasers
