Carbon dots decorated graphene oxide nanosheets prepared by a novel technique with enhanced nonlinear optical properties

AIP Advances, 2019
We report a novel technique to synthesize fluorescent carbon dots decorated graphene oxide (CDs-GO) sheets by microwave irradiation using citric acid as the precursor and ethylenediamine as the passivation agent.

Nanotube-based systems for broadband optical limiting: towards an operational system

, 2005
Nanotube-based systems are good candidates for optical limiting against broadband laser pulses. We explore new routes to improve their limiting performances. We show that the diameter of the nanotubes is a key factor to control the performances.
