摘要
碳点是一种新型荧光纳米材料,因其生物相容性好、发光效率高而被人们所熟知,是可以替代量子点的良好候选者。其独特的发光机理也是大家探究的热门内容。利用特定波长的激光漂白了不同碳化程度的碳点,探究了碳点的碳化程度与发射波长及抗光漂白稳定性的关系,为设计合成具有抗漂白稳定性能力的碳点提供了基础。
As a new kind of carbon material,carbon dots is well known for the excellent optical properties and good biocompatibility.It is a hot topic to explore unique wavelength dependence luminescence mechanism.In this paper,we use a specific wavelength of laser to bleach carbon dots with different degrees of carbonization,and explore the relationships among the degree of carbonization,emission wavelength of the carbon dots and the stability against photobleaching.Above basic research is very important for designing and synthesizing carbon material with high stability against photobleach.
