Abstract

Shrimp shells are used as the carbon and nitrogen source to produce high-fluorescence nitrogen-carbon dots at room temperature by employing a cutting process based on NaCl crystals without added nitrogen-doped agents. The synthesis process is rapid (<5 min) and easy. The synthesized nitrogen-doped carbon dots (NCDs) are characterized using photoluminescence (PL) spectroscopy, transmission electron microscopy (TEM), scan electron microscopy (SEM), Fourier-transform infrared (FTIR) spectroscopy, and energy dispersive X-ray (EDX) analysis. The synthesized NCDs exhibit high fluorescence and are effectively used in the instant and fast detection of tea freshness.
燃烧虾壳复合溶液在室温下低能耗快速合成高荧光氮掺杂碳点及其在儿茶素检测中的应用
以虾壳为碳氮源,采用不添加氮掺杂剂的NaCl晶体切割工艺,在室温下制备高荧光氮碳点。合成过程快速(5分钟),操作简单。利用光致发光(PL)光谱、透射电子显微镜(TEM)、扫描电子显微镜(SEM)、傅里叶变换红外(FTIR)光谱和能量色散x射线(EDX)分析对合成的氮掺杂碳点(NCDs)进行了表征。合成的NCDs具有高荧光特性,可有效地用于茶叶新鲜度的即时快速检测。
