摘要

高度的分子对称性使其能带间的电子跃迁被禁止

导致其发光很弱。为了提高C

纳米晶的发光强度

采用挥发C

的芳香烃饱和溶液的方法

一步合成了芳香烃溶剂化的C

纳米晶。实验结果表明

有机溶剂的掺杂在不同程度上增强了C

纳米晶的发光

其原因可能是溶剂的掺杂破坏了C

的高度的分子对称性。

Abstract

The luminescence intensity of initial fullerene is very low because of its high molecular symmetry. The key point to enhance the luminescence intensity of fullerene is to lower the molecular symmetry of fullerene

which could make the forbidden bands transition allowed. Herein

nano/microcrystals were synthesized by the evaporation of C

saturated solution in

-xylene

3-trichlorobenzene

4-trichlorobenzene

and 1

5-trichlorobenzene. The structures of C

nanocrystals were controlled and their PL intensities were also highly enhanced by the introduction of different solvent.
