摘要

以杯状块（天然橡胶）为碳源，经200℃水热处理18 h制备了碳点（CDs）。为了改善CDs的光学性能，采用过硫酸铵进行化学掺杂。考察了两种溶剂（去离子水和甲酰胺）用于CD合成以提高杯状团块的溶解度。用甲酰胺（FCDs）制备的CDs比用去离子水（ACDs）制备的CDs粒径大。甲酰胺可以促进反应过程中的电子转移，从而增强水热处理和改善光学性质，从而实现量子产率。最后，FCDs可作为荧光墨水应用，具有较高的荧光稳定性。

Effect of chemical doping and solvent on the optical properties of carbon dots from cup lump for making fluorescent ink

Carbon dots (CDs) were prepared from cup lump (natural rubber) as a carbon resource using hydrothermal treatment at 200 °C for 18 h. In order to improve the optical properties of CDs, ammonium persulfate was used for chemical doping. Two kinds of solvent were evaluated (deionized water and formamide) for CD synthesis to enhance the solubility of cup lump. The particle size of CDs obtained using formamide (FCDs) was larger than that obtained using deionized water (ACDs). Formamide could facilitate electron transfer during the reaction, resulting in an enhanced hydrothermal treatment and improved optical properties to achieve the quantum yield. Finally, the FCDs could be applied as a fluorescent ink with a high stability fluorescence.

期刊介绍： Materials Research Bulletin is an international journal reporting high-impact research on processing-structure-property relationships in functional materials and nanomaterials with interesting electronic, magnetic, optical, thermal, mechanical or catalytic properties. Papers purely on thermodynamics or theoretical calculations (e.g., density functional theory) do not fall within the scope of the journal unless they also demonstrate a clear link to physical properties. Topics covered include functional materials (e.g., dielectrics, pyroelectrics, piezoelectrics, ferroelectrics, relaxors, thermoelectrics, etc.); electrochemistry and solid-state ionics (e.g., photovoltaics, batteries, sensors, and fuel cells); nanomaterials, graphene, and nanocomposites; luminescence and photocatalysis; crystal-structure and defect-structure analysis; novel electronics; non-crystalline solids; flexible electronics; protein-material interactions; and polymeric ion-exchange membranes.
