Abstract
The emergence of "green" materials has been attracting significant attention along the last few years for various applications. Here, we report a rapid, efficient and reproducible microwave-assisted synthesis of graphene quantum dots GQDs of identical features whatever the nature of biomass wastes investigated. The synthesized GQDs were fully characterized by X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, transmission electron microscopy and dynamic light scattering. The nanoparticles display narrow size of some nanometers with crystal lattices. Furthermore, the water-soluble particles show excitation-dependent photoluminescence ranging from blue to orange emission wavelength in solution. Interestingly, thin films display white light emission under 325 nm UV-light excitation, while aggregation-induced quenching is usually observed.
