摘要
本文以无水柠檬酸和3-羟基-N,N-二甲基苯胺为原料通过一步水热法制备了具有长波长发射的荧光碳点(CD),通过紫外及荧光光谱仪,红外光谱仪,透射电子显微镜和小角X射线散射仪对其理化性质进行表征,并探究其在光电转换和细胞成像方面的应用.结果表明:该CD为粒径大小分布均匀的球形颗粒,具有较低的生物毒性,良好的光电转换及细胞成像能力.
Abstract
Fluorescent carbon dots(CDs)with long-wavelength emission were prepared in a one-step hydrothermal process using anhydrous citric acid and 3-hydroxy-N,N-dimethyl aniline as precursors.The physicochemical properties of the CDs were characterized by UV-visible spectrophotometry,fluorescence spectroscopy,Fourier-transform infrared spectroscopy,transmission electron microscopy,and small-angle X-ray scattering.Investigations into their applications in photovoltaic conversion and cellular imaging were also carried out.The results showed that the CDs were spherical particles with uniform size distribution,possessed low cytotoxicity,and had good performance in photovoltaic conversion and cellular imaging.
