Abstract

, outperforming many benchmark 2D materials, including graphene, TMDCs and MXenes. Density functional theory analysis indicates that the enhanced two-photon absorption in 2D rhodonite arises from the contributions of Fe orbitals originating from electronic states near the Fermi level. In addition, the increased probability of two-photon absorption can also be attributed to transitions between orbitals of similar character with strong contributions, which occur as a result of the hybridization between Si and O p orbitals. These findings position 2D rhodonite as a highly promising candidate for next-generation photonic technologies, including optical switching, 3D microfabrication, and quantum information processing.
