量子点发光二极管及其制备方法和复合材料
Abstract:
一种量子点发光二极管，包括阳极、阴极以及位于所述阳极和所述阴极之间的量子点发光层，所述阳极和所述阴极之间设置有载流子功能层，所述载流子功能层含有磁性材料。因磁性材料可以调节载流子迁移率（如空穴迁移率或电子迁移率），从而改善载流子的注入平衡，因此，将该载流子功能层设在量子点发光二极管器中可以有效提高器件的发光效率和稳定性。
Abstract(English):

A quantum dot light emitting diode, comprising an anode, a cathode, and a quantum dot light emitting layer between the anode and the cathode. A carrier functional layer is provided between the anode and the cathode, and the carrier functional layer contains a magnetic material. The magnetic material can adjust the carrier mobility (such as hole mobility or electron mobility), thereby improving the injection balance of carriers. Therefore, the carrier functional layer is provided in a quantum dot light emitting diode device, effectively improving the light emitting efficiency and stability of the device.
