摘要

钙钛矿发光二极管在显示和照明领域受到了广泛的关注,特别是在需要高效率和高亮度的应用中。与低维钙钛矿相比,三维钙钛矿发光二极管有望实现更高的亮度,但由于在多a -阳离子钙钛矿的无序结晶过程中形成缺陷,高效的蓝色三维钙钛矿发光二极管仍然是一个挑战。在这里,我们展示了一种全位合金方法,使甲脒和铯杂化钙钛矿的顺序a位掺杂生长成为可能。这种方法显著降低了钙钛矿薄膜的陷阱密度,大约降低了一个数量级。因此,我们获得了高效明亮的蓝色钙钛矿发光二极管,其外部量子效率为23.3%,发光效率为33.4 lm W−1,发光亮度约为5700 cd m−2,峰值为487 nm。这项工作为制备高质量的多组分钙钛矿提供了一种策略。

All-site alloyed perovskite for efficient and bright blue light-emitting diodes

All-site alloyed perovskite for efficient and bright blue light-emitting diodes

Perovskite light-emitting diodes have drawn great attention in the fields of displays and lighting, especially for applications requiring high efficiency and high brightness. While three-dimensional perovskite light-emitting diodes hold promise for achieving higher brightness compared to low-dimensional counterparts, efficient blue three-dimensional perovskite light-emitting diodes have remained a challenge due to defect formation during the disordered crystallization of multiple A-cation perovskite. Here we demonstrate an all-site alloy method that enables sequential A-site doping growth of formamidinium and cesium hybrid perovskite. This approach significantly reduces the trap density of the perovskite film by approximately one order of magnitude. Consequently, we achieve efficient and bright blue perovskite light-emitting diode with an external quantum efficiency of 23.3%, a luminous efficacy of 33.4 lm W−1, and a luminance of approximately 5700 cd m−2 for the emission with a peak at 487 nm. This work provides a strategy for growing high-quality multicomponent perovskite for optoelectronics.
