摘要

采用微波法制备了氮掺杂碳纳米点。通过调控碳纳米点中氮元素的掺杂含量和表面的化学环境，实现了对碳纳米点发光特性的调控。在此基础上，可实现完全基于氮掺杂碳纳米点的荧光墨水、比率型荧光探针及光泵浦激光。研究目的在于探索氮掺杂碳纳米点的发光机理，揭示影响碳纳米点荧光量子效率的因素及其在生物成像、传感、防伪、信息存储、激光等领域的应用。

Abstract

Nitrogen-dopped carbon nanodots are emerging stars in carbon-based nanomaterials. Herein

we introduce our works on nitrogen-dopped nanodots

which were prepared through one-step microwave synthesis route. Our works demonstrated that the optical properties of the carbon nanodots can be modulated by nitrogen dopping concentrations and surface chemical environments

and realize carbon-nanodot-based fluorescent inks

ratiometric fluorescent nanosensor and optical pumped laser. Our studies aim at exploiting the luminescent mechanism of the nitrogen-dopped carbon nanodots

revealing the influencing factors on their luminescent quantum yields and their applications in bioimaging

sensing security

information storage

lasers and so on.
