【摘要】本文把 Mg F2 引入有机电致发光器件的电子传输层和空穴传输层之间 ,制备了有机 -无机复合的电致发光器件。通过发光和电学研究发现 ,Mg F2 层的引入可以明显抑制激基复合物的形成 ,增加短波长光的发射的强度 ;同时 ,它对降低起亮电压 ,改善器件发光性能具有明显的效果更多还原

【Abstract】 We introduced MgF 2 between the hole transport layer and electron transport layer of organic electroluminesence device and made organic inorganic hybrid devices.We studied the luminescent and electrical properties and find that MgF 2 can suppress the formation of excimer,increase the emission of short wavelength.In the mean time,it can efficiently lower the turn on voltage and improve the properties of the devices.更多还原
