Study on the iron oxide/glass nanocomposite materials: fabrication, microstructure and ultrafast nonlinear optical properties

摘要: Herein, novel composite glass materials are synthesized by a facile sol–gel approach accompanied with controlled atmosphere, in which inexpensive iron oxide nanoparticles (NPs) introduced into sodium borosilicate glasses host. By defining temperature and time limits, two NPs different chemical valence (Fe2O3 Fe3O4 NPs) were produced the The incorporation of matrix vouchsafe obtained excellent nonlinear optical response. Thus, Z-scan method using ultrafast femtosecond laser pulse as fast 190 fs was employed to evaluate feature as-derived glasses, exhibiting self-focusing effect reverse saturable absorption. In addition, we have added new physics analysis mechanism on effects paper. results imply that these promising candidates for future development devices.
