摘要

以热解石墨为原料

利用电化学方法

制备了荧光碳纳米颗粒。系统地研究了在不同浓度、时间、pH值、温度等条件下

离子对碳纳米颗粒荧光发射规律的影响。实验结果表明:Pb

离子不改变光谱形状

但可以降低荧光峰值强度;Pb

离子作用荧光碳纳米颗粒的时间越长

猝灭效率越低;pH值不同

猝灭效率不同;随着温度的升高

离子对碳纳米颗粒荧光的猝灭效率逐步提高。其猝灭机理可能为电荷转移猝灭和动态猝灭。

Abstract

Fluorescent carbon nanoparticles were prepared by electrochemical methods using pyrolytic graphite as raw materials. The effects of lead ion solutions with different concentrations on light emission of carbon nanoparticles were systematically investigated and the roles of reaction time

pH values

and temperature played were also considered in this paper. Experimental results show that lead ions can change the intensity of photoluminescence (PL) from carbon nanoparticles rather than its spectral shape. The effects of lead ions on PL of carbon nanoparticles reduce with the increase of reaction time

and change with pH values. In addition

the higher temperature can strengthen the effects of lead ions on PL intensity of carbon nanoparticles. The possible mechanism could be attributed to charge transfer and Brownian movement.
