Abstract Antimonene has been found to possess excellent nonlinear refractive and saturable absorption properties recently. To further investigate its optical limiting properties, we prepared uniform antimonene quantum dots (AMQDs) via a facile ionic liquid-assisted exfoliation method. Thereafter the nonlinear absorption of the atomically thin AMQDs was studied using the open aperture Z-scan technique in the nanosecond laser pulse regime. Z-scan measurements indicate that the prepared AMQDs exhibited superior optical limiting properties at 532 nm and 1064 nm excitation, implying the antimonene hold potential for developing broadband nonlinear optical devices.
