以焦性没食子酸为碳源,采用溶剂热法在N,N-二甲基甲酰胺(DMF)中合成了绿色荧光碳点(CDs)。在CDs的形成过程中,DMF不仅作为溶剂参与反应,而且作为氮源参与反应。同时,它促进了CDs中大共轭sp2结构域的形成。所制备的CDs平均尺寸为11.9 nm,发射中心为520 nm,荧光量子产率为16.8%。在实际应用中,将CDs/N-[3-(三甲氧基硅基)丙基]乙二胺(oh -792)混合物与UV芯片相结合,制备出暖白光二极管,其色坐标为(0.39,0.47),相关色温为4323 K,适合室内照明。采用溶剂热法合成的绿色发光碳点用于暖白色发光器件。
Green fluorescent carbon dots (CDs) were synthesized with pyrogallic acid as carbon source by solvothermal method in N,N-dimethylformamide (DMF). During the formation of the CDs, DMF not only serves as solvent for reaction, but also as nitrogen source to participate in the reaction. At the same time, it promotes the formation of large conjugated sp2-domain in CDs. The prepared CDs have an average size of 11.9 nm, excitation-independent emission centered at 520 nm and fluorescence quantum yield of 16.8%. For practical applications, warm white light-emitting diodes were fabricated by combining the CDs/N-[3-(trimethoxysilyl)propyl]ethylenediamine (KH-792) mixture with UV chip, which emitted warm white light with color coordinates of (0.39, 0.47) and a correlated color temperature of 4323 K suitable for indoor lighting. Green emissive carbon dots synthesized by solvothermal method is used for warm white light-emitting devices.
