钙钛矿纳米晶体由于其易于合成和优异的光电性能，在柔性发光二极管（led）中显示出巨大的潜力。在柔性led领域，为不同的应用选择衬底仍然是一个关键问题。本文报道了一种以聚甲基丙烯酸甲酯（PMMA）改性印刷纸为基材的高柔性红发钙钛矿发光二极管（PeLED）。在印刷纸/PMMA衬底上制备的柔性发光二极管的最大亮度为1330 cd/ $\text{m}^{{2}}$，最大外量子效率（EQE）为8.5%。衬底到纸张的延伸将扩大pled在极其灵活和廉价的应用中的机会。
Perovskite nanocrystals (NCs) have shown great potential in flexible light-emitting diodes (LEDs) due to their ease of synthesis and excellent optoelectronic properties. In the field of flexible LEDs, the selection of substrate for different applications is still a key issue. Herein, we report a highly flexible red-emitting perovskite light-emitting diode (PeLED) by utilizing Polymethyl methacrylate (PMMA) modified printing paper as substrates. The flexible PeLEDs on printing paper/PMMA substrate exhibited a maximum luminance of 1330 cd/ $\text{m}^{{2}}$ and a maximum external quantum efficiency (EQE) of 8.5%. This extension of substrate to paper will widen the opportunity of PeLEDs in extremely flexible and inexpensive applications.
