| 中文摘要: |
| 目的 通过水热合成法制备黄色荧光碳点，开发一种在特定波长光激发下能够发出黄色荧光的碳点油墨。方法 以氨基苯磺酸和邻苯二胺为前驱体，乙醇为溶剂，采用水热合成法制备黄光碳点，并对其光学性能(如吸收光谱和荧光光谱)及结构组成(如粒径分布和晶体结构)进行详细表征。然后以制备的黄光碳点为功能材料，聚乙烯醇为连接料，添加适量助剂，配制成黄光碳点油墨，并系统评估它在不同激发光源下的光学性能、稳定性及在不同印刷基材上的印刷效果。结果 通过优化碳点油墨的配方和印刷工艺，所产生的黄色荧光不仅具备高亮度和稳定性，还能在纸基材料上呈现一致的视觉效果，激发波长从300 nm向400 nm红移，显示出显著的波长依赖性。结论 在油墨中加入荧光碳点，既能保持碳点的荧光强度，又能强化油墨在实际应用中的性能与效果，在高性能光学材料、功能性油墨以及印刷防伪等领域具有广阔的应用前景。 |
| 英文摘要: |
| The work aims to develop a carbon dot ink capable of emitting yellow fluorescence under the excitation of light at specific wavelengths by preparing yellow fluorescent carbon dots with a hydrothermal synthesis method. Yellow carbon dots were prepared by hydrothermal synthesis with aminobenzenesulfonic acid and o-phenylenediamine as precursors and ethanol as a solvent, and their optical properties (e.g., absorption and fluorescence spectra) and structural compositions (e.g., particle size distribution and crystal structure) were characterized in detail. Subsequently, with prepared yellow carbon dots as the functional materials and polyvinyl alcohol as the linker, appropriate amount of additives were added to formulate the yellow carbon dot inks, and their optical properties and stability under different excitation light sources as well as their printing effects on different printing substrates were systematically evaluated. By optimizing the formulation and printing process of the carbon dot inks, the resulting yellow fluorescence not only possessed high brightness and stability, but also presented a consistent visual effect on paper-based materials, with the excitation wavelength red-shift from 300 nm to 400 nm, showing a significant wavelength dependence. This study demonstrates that by adding fluorescent carbon dots to inks, both the fluorescence intensity of the carbon dots can be maintained and the performance and effect of the inks in practical applications can be enhanced. Therefore, it has a broad application prospect in the fields of high-performance optical materials, functional inks, and printing anti-counterfeiting. |
