| 摘 要： | 利用红、绿、蓝三基色量子点材料作为发光层，使用旋涂法实现了3 种颜色的量子点发光二极管的制备。选择合适材料和溶剂形成各功能层薄膜，通过改变量子点溶液的浓度来调控器件的光电性能。对不同浓度下的量子点溶液制备的三色器件进行测试和比较，得到3 种颜色量子点溶液的合适浓度，使最终制备的三基色发光器件具有相同的制备工艺和相当的发光亮度，其亮度均可达到104cd/ m2的量级，为后续使用喷墨打印法来实现三基色QLED 提供理论和实践基础。

| Abstract: | Three-color quantum dot light-emitting diodes (QLED) were prepared by the spin-coating method with red, green and blue quantum dots as the light-emitting layer. Suitable materials and solvents were selected to form each functional layer film to regulate the photoelectric performances of the devices by changing the concentration of quantum dot solution.The three-color devices prepared by quantum dot solution at different concentrations were tested and compared to obtain the appropriate concentration of three-color quantum dot solution,so that the final three-primary-color light-emitting devices have the same preparation process and equivalent luminance, and its luminance can reach the order of 104cd/m2. It provides a the oretical and practical basis for the subsequent use of inkjet printing method to realize the three-primary-color QLED. |
