Abstract

To address sustainability and recyclability challenges in nonlinear optical limiting (NOL), we develop an eco-friendly magnetic graphene oxide (MGO)-water suspension. At 0.03 mg/mL, it exhibits strong NOL effects at 1064 and 532 nm, with maximum NOL capability coefficients of 0.535 and 0.556, and minimum transmittances of 0.225 and 0.229, respectively. Mie scattering is the primary mechanism. The suspension shows excellent dispersibility, stability, high damage threshold, and magnetically assisted recoverability, offering a promising material for practical NOL applications.
