摘要题目碳量子点的合成、性质及应用

1、第二届“纳米科学前沿论坛” 分子纳米结构与纳米技术实验室摘要题目 碳量子点的合成、性质及应用 报告人： 黄佩佩黄佩佩，女，1988年3月出生，山东菏泽人，2011年9月考入中科院化学研究所，现在中科院化学所分子纳米科学与纳米技术实验室宋卫国研究员课题组从事纳米吸附材料合成及对重金属离子吸附性能研究的工作。摘要内容(Introduction)量子点，又称作半导体纳米微晶体，在光学、磁学、催化学、生物医药及功能性材料等领域有着广泛的应用前景1-5。但是，该类材料在高浓度或紫外照射下易分解，会释放出致命的重金属离子，对生物体及环境造成潜在的威胁，因此寻找具有类似光学性质的良性纳米材料成为了该领域科研

2、工作者的研究焦点6-9,11。碳作为地球上含量最丰富的元素之一，其新的存在形式-碳量子点，不仅能够发射稳定的长寿命荧光还具有宽的激发波长范围，可作为生物标记物对生物体进行长时间及多样品的同时检测；而且经表面修饰或掺杂处理后，其荧光发射量子产率可与高性能半导体量子点媲美；最重要的是，它较以往的荧光材料更具有生物安全性，比其他荧光标记物对生物分子的活性干扰小。碳量子点的优异性除了体现在生物荧光标记方面外，通过改变引入到其表面的官能团种类来调控其光电性质、溶解性及与各种界面的相宜性等参数，碳量子点也将在制备磁共振成像的造影剂、磁数据存储、光电转换及光催化领域10-14大放异彩。参考文献：1 Peng
