Abstract

Carbon nanodots (CDs) synthesized via the microwave pyrolysis approach are monodisperse with the nano-size distribution. The CDs show color tunability simply by changing the excitation wavelength. Also, the emission intensity varies with varying different microwave response times. Detail characterizations indicate that the carbon defects that lead to heterogeneous emission levels are responsible for the emission properties of the CDs.

碳纳米点的激发依赖发射机制
微波热解法制备的碳纳米点呈单分散、纳米级分布。通过改变激发波长,CDs显示出颜色的可调性。发射强度随微波响应时间的变化而变化。详细表征表明,导致非均匀发射水平的碳缺陷是CDs发射特性的原因。
