A cellulose paper is used impregnated with light-emitting CdTe nanocrystals and carbon dots, and filled with a polyurethane to fabricate uniform transparent composite films with bright photoluminescence of red (R), green (G), and blue (B) (RGB) colors. A building brick-like assembly method is introduced to realize RGB multicolor emission patterns from this composite material. By sectioning out individual pixels from monochrome-emissive composite sheets, the advantage of the self-healing properties of polyurethane is taken to arrange and weld them into a RGB patterned fabric by brief exposure to ethanol. This provides an approach to form single layer RGB light-emitting pixels, such as potentially required in the display applications, without the use of any lithographic or etching processing. The method can utilize a wide range of different solution-based kinds of light-emitting materials.
使用浸有发光碲化镉纳米晶体和碳点的纤维素纸，并填充聚氨酯，以制造具有红色（R）、绿色（G）和蓝色（B）（RGB）明亮光致发光的均匀透明复合薄膜。引入一种类似建筑砖块的组装方法，以实现这种复合材料的RGB多色发射图案。通过从单色发射复合片材中分割出单个像素，利用聚氨酯的自修复特性，通过短暂暴露于乙醇将它们排列并焊接成RGB图案织物。这提供了一种形成单层RGB发光像素的方法，例如在显示应用中可能需要的，而无需使用任何光刻或蚀刻工艺。该方法可以利用各种不同的基于溶液的发光材料。
