title: Preparation of carbon dots by non-focusing pulsed laser irradiation in toluene.
abstract: A simple approach for preparing carbon dots (CDs) by non-focusing pulsed laser irradiation in toluene was presented. The as-prepared CDs were graphite dots, which were formed by ablating the intermediate graphene. The size of the as-prepared CDs could be easily controlled by the input of laser fluence. The mechanism of the photoluminescence was also discussed.
