金钱草碳量子点的制备及应用研究
|
摘要
本实验以金钱草为原料,采用一步水热法制备稳定性好、水溶性好的蓝紫色碳量子点(CDs)。采用紫外可见光谱和荧光光谱对该CDs进行了光学表征,研究不同离子对碳量子的荧光强度的影响。结果表明,金钱草CDs的荧光强度稳定性好,耐酸耐碱,耐光漂白,可用于痕量检测Fe~(3+)。
The blue-purple fluorescent carbon quantum dots with good stability and water-solubility were prepared by one-step hydrothermal method using chrysanthemum chrysanthemum as raw material. The carbon quantum dots were characterized by UV-Vis and fluorescence spectra. The influence of different ions on the fluorescence intensity of carbon quantum dots was studied. The resμLts showed that the carbon quantum dots have good stability, acid and alkali resistance, light bleaching resistance, and can be used for trace detection of Fe~(3+).
