摘要:We present highly efficient colloidal core-shell quantum dots, quantum rods and perovskite nanocrystals for energy-saving quality display and lighting applications. We applied these luminescent materials to make various devices including luminescent microspheres for on-chip InGaN LED packaging (photoluminescent applications), Using of electrospin technology to make  aligned quantum rod containing film for polarized light emission, and making use of these materials as the emissive layer in solution processed quantum dot LED and perovskite LED (electroluminescent applications). In the photoluminescent applications, we were able to achieve high stable quantum dot composites called luminescent microspheres, which were tested for on-chip InGaN LED packaging. The output of the packaged LED was stable for more than 4000 hours under continuous operation, demonstrating a robust method of applying quantum dot for on-chip LED packaging. In the electroluminescent applications, we demonstrated a mixed-cation perovskite based perovskite-LED. With optimized composition, the LEDs exhibited encouraging performance with the highest reported luminance of 55005 cd m-2 and a current efficiency of 10.09 cd A-1. It is anticipated that luminescent semiconducting nanocrystals will shake or even revolute the display and lighting industry; a new era of nanocrystals is coming.
