Lead-free PEASnI-based perovskite LEDs are successfully inkjet-printed on rigid and flexible substrates. Red-emitting devices (λ = 633 nm) exhibit, under ambient conditions, a maximum external quantum efficiency (EQE) of 1% with a related brightness of 30 cd/m at 10 mA/cm.
无铅的基于PEASnI的钙钛矿发光二极管已成功通过喷墨印刷在刚性和柔性基板上。在环境条件下,发红光的器件(λ = 633 nm)在10 mA/cm²时表现出1%的最大外量子效率(EQE),相关亮度为30 cd/m²。
