一种碳量子点的制备及其实验设计

Preparation of Carbon Quantum Dots and Designation of Experiments

采用明胶作为碳源,乙二胺作为氮源,通过简单的水热法成功合成了一种碳量子点,并利用其独特的尺寸和光学性质,设计了三个具有科普意义的趣味小实验:碳贯而行、碳印生徽、碳为观指。实验简单易行,生动有趣,无需受场地限制,可在不同年龄段的学生中展示,也适用于公众演示。

This paper utilized gelatin as the carbon source and ethylenediamine as the nitrogen source to successfully synthesize a novel type of carbon quantum dots using a simple hydrothermal method.Leveraging their unique size and optical properties,three scientifically engaging and entertaining experiments were designed Carbon Through and Through,Carbon Print Shines Bright and Carbon as the Viewer's Guide.These experiments are simple,fun,and versatile,not limited by location,suitable for showcasing among students of different age groups,as well as for public demonstrations.
