摘要

以葡萄糖为碳源，通过水热法制备了碳量子点，并通过X射线衍射（XRD）、透射电镜（TEM）、紫外-可见吸收光谱、荧光光谱和傅里叶红外光谱（FTIR）等方法对样品的结构、形貌和光学性能进行表征。结果显示：以葡萄糖为碳源制备的碳量子点近似球形，大小均匀，分散性良好，无团聚现象。其发射波长依赖于激发波长，在紫外灯下发出明亮的绿光。

Abstract

Carbon nanoparticles were synthesized

via

hydrothermal oxidation of glucose. The carbon dots were characterized by X-ray diffraction (XRD)

transmission electron microscopy (TEM)

ultraviolet-visible spectrophotometry

fluorescene spectrophotometry and Fourier transform infrared spectrophoto-metry (FTIR). The results indicate that the carbon dots have appropriate spherical morphology

uniform size

good dispersion

non-agglomeration. The carbon dots can emit bright green photoluminescence under UV excitation

and exhibit excitation-dependent PL behavior.
