Size-dependent two-photon absorption and ultralow optical-limiting response in atomically-thin rhodonite

2D rhodonite shows strong size-dependent NLO behavior, with enhanced 2PA and an ultralow OL threshold. Dimensional reduction strengthens orbital transitions, making it a promising material for next-generation photonic technologies.
