摘要

在反相微乳液体系中

以抗坏血酸作为碳源制备具有高强度荧光的碳量子点.实验中通过调整水和表面活性剂的量比实现对碳量子点尺寸大小的控制

利用十六烷基胺修饰碳量子点.当激发波长为360 nm时

碳量子点的量子产率最高为47%.当水和表面活性剂的量比从20增加到50时

碳量子点的尺寸也随之而增大.

Abstract

Highly luminescent carbon quantum dots (CQDs) were prepared by using L-ascorbic acid as a carbon source derived from reverse microemulsion. This method could control the CQDs size directly by adjusting water-surfactant molar ratio without other procedure. Hexadecylamine was used to functionize CQDs. The synthesized CQDs had high quantum yield of maximum 47% at the 360 nm excitation wavelength and the particle size could be tuned by changing the molar ratio of the water to surfactant from 20 to 50.
