摘要：

In this work, we report on new results regarding the nonlinear optical response and the optical limiting action of few layered graphene oxide dispersed in various organic solvents, such as N,N-Dimethylformamide (DMF), Tetrahydrofuran (THF), (N-Methyl-2-Pyrrolidone (NMP), Chlorobenzene (CB), 1,2-Dichlorobenzene (o-DCB), and 1-Chloronaphthalene (CN). Few layered graphene oxide was found to exhibit saturable absorption for low incident intensity and reverse saturable absorption at higher intensity. Its nonlinear absorption was found to be significantly larger than that of single layer graphene oxide, depending upon the solvent used becoming maximum for heavier solvents like e.g. CN and o-DCB. The present results are discussed and compared with other literature reports. (C) 2013 Elsevier B.V. All rights reserved.
