A milestone in the field of organic luminescent labeling is reached, as fast and multiple (>40 cycles) printing of information onto any substrate in any size for very low costs is shown, resulting in rewritable high-resolution (>700 dpi) and high-contrast images. By making use of a simple device structure containing nothing but highly available materials, an ultrathin, flexible, and fully transparent layer stack was realized. Using light alone, any luminescent image can be printed into and erased from this layer contactless and without the need of any ink. Compared to existing approaches, the demonstrated concept represents a promising method for production of luminescent on-demand tags with the potential to supersede conventional labeling techniques in many ways.
有机发光标记领域迎来了一个里程碑，因为展示了以极低的成本在任何尺寸的任何基材上快速且多次（>40次循环）打印信息，从而产生可重写的高分辨率（>700 dpi）和高对比度图像。通过使用一种仅包含极易获得材料的简单器件结构，实现了超薄、柔性且完全透明的层堆叠。仅使用光，任何发光图像都可以非接触方式打印到该层中并从该层擦除，无需任何墨水。与现有方法相比，所展示的概念代表了一种生产按需发光标签的有前景的方法，有可能在许多方面取代传统标记技术。
