Stable perovskite LEDs

金属卤化物钙钛矿发光二极管（led）与商用oled一样高效，并能提高颜色纯度。然而，它们的长期稳定性远远不如oled，因此标志着工业发展的最大挑战。在这个项目中，学生将研究钙钛矿led中发生的关键降解过程，并创建新的和改进的器件架构来克服这些降解。一个中心目标是在博士结束时将目前T50的寿命从10小时提高到1000小时。该博士生将接受材料合成、薄膜和器件制造、LED表征、先进光谱学和材料表征技术（如电子显微镜和x射线衍射）方面的培训。

Metal halide perovskite light emitting diodes (LEDs) are as efficient as commercial OLEDs and produce improved colour purity. However, their long term stability is vastly inferior to OLEDs and thus marks the biggest challenge for industrial development. In this project, the student will investigate the key degradation processes occurring in perovskite LEDs and create new and improved device architectures to overcome these degradations. A central target is to improve the present T50 lifetime from 10s of hours to 1000s of hours by the end of the PhD. The PhD student will be trained in materials synthesis, thin film and device fabrication LED characterisation and advanced spectroscopy and materials characterisation techniques such as electron microscopy and X-ray diffraction.
