dc.description.abstractStable and efficient optical limiters for eye and sensor protection have been in great demand ever since the advent of high-power lasers. In this study, we report the preparation of highly stable hematene nanoflakes for optical limiting applications by a facile exfoliation method from a low-cost, non-van der Waals material. Optical and structural characterization has been carried out to confirm the structure, morphology, and composition of the hematene nanoflakes. Open aperture Z-scan measurements have been carried out in near-transparent samples (87% linear transmission at the excitation wavelength of 532 nm), using 5 ns laser pulses. Despite the high transparency of the sample, a high nonlinear absorption coefficient of up to 13.0 ± 1.1 cm GW–1 has been determined, signifying the potential of this material for fabricating highly efficient optical power limiting devices.en_US
