电化学方法调控荧光碳点的研究
Electrochemical Engineering of Carbon Nanodots
摘要
Abstract
Carbon nanodots(CNDs),as zero-dimensional carbonaceous fluorescent nanomaterials,are valuable add-ons to the current cohorts of fluorescent nanoparticles.The fine control over the size and the surface is the key to gain designated photophysi-cal properties of CNDs as well as empowers CNDs in many applications.Herein,a series of electrochemical strategies to manipu-late the size and the surface of CNDs and to identify the surface structures was presented.Accordingly,the understandings on the originals of photoluminescence as well as the pathways of electrochemiluminescence of CNDs were revealed.These studies demonstrated that electrochemical methods were easy to operate,cost-effective and efficient in altering thin layers of the surface on CNDs within a few nanometers.The key findings in the luminescence mechanism provided guidelines for the rational design of CNDs with suitable features,which could promote applications of CNDs in bioimaging,sensing and catalytic conversion.关键词
