Abstract
⺠Aggregation of CDG (chemically derived graphene) occurs, when its concentration>10 μg/mL. ⺠Self-rolling up of CDG sheets occurs and forms carbon nanoscrolls, when its concentration <10 μg/mL. ⺠The optical properties of carbon nanoscrolls were discussed for the first time. ⺠CDG aggregation (CDGA) causes the decrease of absorptivity, the change of band shape. ⺠CDGA induces the decrease of emission efficiency, the shortening of fluorescence lifetime. ⺠CDGA causes the relative increase of the contribution from short-lived emitting species.
