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
C
60
nano/microcrystals were synthesized by the evaporation of C
60
saturated solution in
m
-xylene
1

and 1

5-trichlorobenzene. The structures of C
60
nanocrystals were controlled and their PL intensities were also highly enhanced by the introduction of different solvent.
