采用液氮处理和离心法合成了荧光碳点。通过紫外-可见吸收光谱、荧光光谱和时间分辨荧光光谱，研究了不同浓度、温度、pH和激发波长条件下C点在水溶液中的物理化学性质。C-点发射约350-550 nm之间的宽荧光，并且通过改变激发波长来调谐它们的荧光。将制备的C点应用于水溶液中Fe 3+的检测。光谱数据显示，所制备的C-点用于检测Fe 3+在12.5 μ M至100 μ M的范围内作为荧光传感器。(C)2015 Elsevier B. V.版权所有。
Fluorescent carbon dots (C-dots) were synthesized by a facile method containing liquid N-2 treatment and centrifuge processes. The photophysical properties of the C-dots in an aqueous solution were examined at various conditions such as concentration, temperature, pH and excitation wavelength by using UV-vis absorption, fluorescence and time-resolved fluorescence spectroscopies. The C-dots emitted a broad fluorescence between approximately 350-550 nm and their fluorescence was tuned by changing excitation wavelength. The as-prepared C-dots were applied to Fe3+ detection from aqueous solution. Spectroscopic data revealed that the as-prepared C-dots were used to detect Fe3+ in the range of 12.5 mu M to 100 mu M as a fluorescence sensor. (C) 2015 Elsevier B.V. All rights reserved.
