Carbon quantum dots synthesis by laser ablation of graphene oxide in biocompatible solutions

A biocompatible dispersion of carbon quantum dots (CQDs) has been obtained by laser irradiation of graphene oxide (GO) in liquid media. The CQD synthesis uses a pulsed IR laser operating at 970 nm, with a 100 ms pulse duration and a fluence of 1.1 kJ/cm2. The carbon target consis...
