喷墨打印作为一种有效的制造技术,非常适合于制作下一代显示器中的钙钛矿型发光二极管。然而,利用喷墨打印产生的钙钛矿型发光二极管的效率不令人满意,阻碍了其未来应用的发展。在这里,我们报告了使用喷墨打印的高效PELED,其外量子效率为7.9%,电流效率为32.0cd/A,最高亮度为2465 cd/m2;这些值是文献中喷墨打印的PELED电流效率的最高值之一。我们的设备的突出性能是由于PVK层上没有咖啡环和均匀的钙钛矿型纳米晶层,这是真空后处理和使用合适的墨水所产生的结果。此外,通过调整印刷网点的间距,有效地控制了钙钛矿层的表面粗糙度和厚度。本研究对喷墨打印在PELED制造中的应用进行了深入的探索,这是未来PELED工业化生产的最有前途的方法之一。
As an effective manufacturing technology, inkjet printing is very suitable for the fabrication of perovskite light-emitting diodes in next-generation displays. However, the unsatisfied efficiency of perovskite light-emitting diode created with the use of inkjet printing impedes its development for future application. Here, we report highly efficient PeLEDs using inkjet printing, with an external quantum efficiency of 7.9%, a current efficiency of 32.0 cd/A, and the highest luminance of 2465 cd/m2; these values are among the highest values for the current efficiency of inkjet-printed PeLED in the literature. The outstanding performance of our device is due to the coffee-ring-free and uniform perovskite nanocrystal layer on the PVK layer, resulting from vacuum post-treatment and using a suitable ink. Moreover, the surface roughness and thickness of the perovskite layer are effectively controlled by adjusting the spacing of printing dots. This study makes an insightful exploration of the use of inkjet printing in PeLED fabrication, which is one of the most promising ways for future industrial production of PeLEDs.
